[U-Boot] [PATCH 00/12] ns16550: add generic binding to unify the drivers

[U-Boot] [PATCH 00/12] ns16550: add generic binding to unify the drivers

[Thomas Chou]

Add generic binding to unify ns16550 drivers. There are
several drivers using almost the same code, such as serial_dw,
serial_keystone, serial_omap, serial_ppc, serial_rockchip,
serial_tegra.c, and serial_x86. But each is platform specific.

The key difference between these drivers is the way to get
input clock frequency. With this unified approach, fixed clock
frequency should be extracted from "clock-frequency" property of
device tree blob. If this property is not available, the macro
CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a
function to get clock, eg, get_serial_clock().

[U-Boot] [PATCH 01/12] debug_uart: restore ns16550 as default

[Thomas Chou]

Since commit 220e8021af96 ("nios2: convert altera_jtag_uart to
driver model"), the default debug uart was changed. Most people
use ns16550 UART, so restore it as default.

[U-Boot] [PATCH 03/12] ns16550: change map_sysmem to map_physmem

[Thomas Chou]

Change map_sysmem() to map_physmem(), because sandbox is the only
arch which define map_sysmem() and it actually only calls
map_physmem(). For some arch like nios2, the flag should be
MAP_NOCACHE for port access.

Why change it to map_physmem()? Doesn't that make assumptions about
how sandbox is implemented?

[U-Boot] [PATCH 03/12] ns16550: change map_sysmem to map_physmem

The question might be asked from the other side, why does it use 
map_sysmem()?

In README,

- CONFIG_ARCH_MAP_SYSMEM
Generally U-Boot (and in particular the md command) uses
effective address. It is therefore not necessary to regard
U-Boot address as virtual addresses that need to be translated
to physical addresses. However, sandbox requires this, since
it maintains its own little RAM buffer which contains all
addressable memory. This option causes some memory accesses
to be mapped through map_sysmem() / unmap_sysmem().

The map_physmem() serves the same purpose to translate physical address 
to virtual address with the additional flag to take care of cache 
property. Many drivers use map_physmem() since ports access should be 
uncached. As ns16550 is a driver, it should use map_physmem() rather 
than map_sysmem().

Please check this series. Though I run buildman, I don't have a rockchip 
board to test. Thanks.

Can you please add a comment above this option saying that we should
keep DEBUG_UART_NS16550 the first one so that it shows as the default
in the kconfig? This is to give a hint to someone else in the future
who touches this file and avoid any further unwanted changes.

I am not in favor of adding driver options to arch Kconfig. I would
suggest updating NS16550_SERIAL option in driver/serial/Kconfig, like
what was done in X86_SERIAL before:

config NS16550_SERIAL
        default y if X86

These #ifdef is needed during the transition. They will be removed as a 
follow-up of this series.

Some spl build with DM platdata but not of_control. So this is needed.

Thanks for reminding. I was trying to recall how to use this "if". :)

[U-Boot] [PATCH v2 00/13] ns16550: add generic binding to unify the drivers

[Thomas Chou]

Add generic binding to unify ns16550 drivers. There are
several drivers using almost the same code, such as serial_dw,
serial_keystone, serial_omap, serial_ppc, serial_rockchip,
serial_tegra.c, and serial_x86. But each is platform specific.

The key difference between these drivers is the way to get
input clock frequency. With this unified approach, fixed clock
frequency should be extracted from "clock-frequency" property of
device tree blob. If this property is not available, the macro
CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a
function to get clock, eg, get_serial_clock().

v2
  use default in driver Kconfig as suggested by Bin Meng.
  remove extra #ifdef CONFIG_NS16550_SERIAL.
  zap CONFIG_NS16550_SERIAL.
  move CONFIG_SYS_NS16550 to Kconfig.

Thomas Chou (13):
  debug_uart: restore ns16550 as default
  ns16550: change map_sysmem to map_physmem
  ns16550: add generic binding to unify the drivers
  ns16550: unify serial_x86
  ns16550: unify serial_ppc
  ns16550: unify serial_rockchip

  ns16550: unify serial_tegra
  ns16550: unify serial_omap
  ns16550: zap CONFIG_NS16550_SERIAL
  ns16550: move CONFIG_SYS_NS16550 to Kconfig

[U-Boot] [PATCH v2 01/13] debug_uart: restore ns16550 as default

[Thomas Chou]

Since commit 220e8021af96 ("nios2: convert altera_jtag_uart to
driver model"), the default debug uart was changed. Most people
use ns16550 UART, so restore it as default.

[U-Boot] [PATCH v2 02/13] ns16550: change map_sysmem to map_physmem

[Thomas Chou]

Change map_sysmem() to map_physmem(), because sandbox is the only
arch which define map_sysmem() and it actually only calls
map_physmem(). For some arch like nios2, the flag should be
MAP_NOCACHE for port access.

[U-Boot] [PATCH v2 03/13] ns16550: add generic binding to unify the drivers

[Thomas Chou]

Add generic binding to unify ns16550 drivers. There are
several drivers using almost the same code, such as serial_dw,
serial_keystone, serial_omap, serial_ppc, serial_rockchip,
serial_tegra.c, and serial_x86. But each is platform specific.

The key difference between these drivers is the way to get
input clock frequency. With this unified approach, fixed clock
frequency should be extracted from "clock-frequency" property of
device tree blob. If this property is not available, the macro
CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a
function to get clock, eg, get_serial_clock().

The CONFIG_NS16550_SERIAL is used only during the transition and it is 
removed now. It does not need this for efi serial to work.

Thank you again for the review.

Yes, I just checked patch#12 "ns16550: move CONFIG_SYS_NS16550 to
Kconfig" (a huge patchset) and found CONFIG_SYS_NS16550 is not on by
default for x86, so this line in efi-x86 can be removed. Previously I
was thinking the option is still on and if that's the case, this line
in efi-x86 should not be removed otherwise efi-x86 won't work.

[U-Boot] [PATCH v3 00/13] ns16550: add generic binding to unify the drivers

[Thomas Chou]

Add generic binding to unify ns16550 drivers. There are
several drivers using almost the same code, such as serial_dw,
serial_keystone, serial_omap, serial_ppc, serial_rockchip,
serial_tegra.c, and serial_x86. But each is platform specific.

The key difference between these drivers is the way to get
input clock frequency. With this unified approach, fixed clock
frequency should be extracted from "clock-frequency" property of
device tree blob. If this property is not available, the macro
CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a
function to get clock, eg, get_serial_clock().

v2
  use default in driver Kconfig as suggested by Bin Meng.
  remove extra #ifdef CONFIG_NS16550_SERIAL.
  zap CONFIG_NS16550_SERIAL.
  move CONFIG_SYS_NS16550 to Kconfig.
v3
  rebase to u-boot master.
  change log message of "ns16550: change map_sysmem to map_physmem".

[U-Boot] [PATCH v3 01/13] debug_uart: restore ns16550 as default

[Thomas Chou]

Since commit 220e8021af96 ("nios2: convert altera_jtag_uart to
driver model"), the default debug uart was changed. Most people
use ns16550 UART, so restore it as default.

[U-Boot] [PATCH v3 02/13] ns16550: change map_sysmem to map_physmem

[Thomas Chou]

Change map_sysmem() to map_physmem(,,MAP_NOCACHE). Though map_sysmem()
can be used to map system memory, it might be wrong to use it for I/O
ports.  The map_physmem() serves the same purpose to translate physical
address to virtual address with the additional flag to take care of cache
property. Most drivers use map_physmem() since I/O ports access should be
uncached. As ns16550 is a driver, it should use map_physmem() rather
than map_sysmem().

[U-Boot] [PATCH v3 03/13] ns16550: add generic binding to unify the drivers

[Thomas Chou]

Add generic binding to unify ns16550 drivers. There are
several drivers using almost the same code, such as serial_dw,
serial_keystone, serial_omap, serial_ppc, serial_rockchip,
serial_tegra.c, and serial_x86. But each is platform specific.

The key difference between these drivers is the way to get
input clock frequency. With this unified approach, fixed clock
frequency should be extracted from "clock-frequency" property of
device tree blob. If this property is not available, the macro
CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a
function to get clock, eg, get_serial_clock().

-	help
-	  Support NS16550 UART or compatible with driver model. This can be
-	  enabled in the device tree with the correct input clock frequency.
-	  If the input clock frequency is not defined in the device tree,
-	  the macro CONFIG_SYS_NS16550_CLK defined in a legacy board header
-	  file will be used. It can be a constant or a function to get clock,
-	  eg, get_serial_clock().

You are dropping this call. We certainly don't want it for driver
model, but I suspect it will break some PPC boards if they don't have
the clock-frequency in the device tree. Do they?

The configs/ files changed after Tom applied the "move cmd_gpio to 
Kconfig" patch to u-boot/master. The series v3 is rebased to 
u-boot/master after that patch. Please try v2 of this patch, or let Tom 
pick up this series.

Ah, we shouldn't do that with driver model. This should be in some
sort of clock driver. Perhaps we should leave this serial driver along
for now?

I understand a clock driver should be used for driver model. But I would 
suggest that we use this get_serial_clock macro until the clock driver 
for powerpc is ready to get UART clock. This will help things moving 
forwards to driver model.

Thomas

Yes, how do you want to proceed here Simon?  I have all of these (and a
few other things) build-tested now and will be doing some quick sanity
run time testing later.  Thanks!

My first thought would be to leave serial_ppc.c out of the conversion,
but that would be tricky given how the series is structured (with the
temporary CONFIG).

Perhaps a TODO on the #define above since it should be cleaned up, and
we want to make sure no one copies it.

Since you have it ready I think it should go in, with the TODO if you
can manage it.

Regards,
Simon

FYI, this patch causes at least Jetson TK1 to immediately reset at boot 
time. I imagine this affects all Tegra boards, at least those that use 
SPL or those that are ARMv7; my p2371-2180 Jetson TX1 ARMv8 board which 
doesn't use SPL seems to still work.

I guess I'll see if I can pin-point the problem, unless you can spot an 
obvious typo or something like that.

Unfortunately I didn't test this patch.

Things to check:
- for SPL, that the platform data is available somewhere
- clock-frequency and reg-shift are in the device tree

The patch below appears to solve the problem. Any ideas how to fix this 
cleanly? I don't think we want to introduce a CONFIG_SPL_xxx for every 
CONFIG_xxx, yet CONFIG_IS_ENABLED() (e.g. used around 
arch/arm/mach-tegra/board.c's U_BOOT_DEVICE(ns16550_com1) definition) 
seems to require this.

Unfortunately, the patch doesn't revert cleanly, or at least would 
require other more recent patches to be reverted first.

Also, while debugging this I found that U-Boot force-probes any device 
referenced by /chosen/stdout-path even if the DT node is disabled; yet 
more fundamental incorrect DT processing:-( That's why the patch below 
only affects SPL. More fixes to actually enable the serial port in DT 
should be required.

But all serial drivers should be converted to driver model by the end of 
Jan, 2016. The DM_SERIAL should be removed then.

As SPL might not use OF_CONTROL. We might need better logic in tegra 
board.c like,
   SPL_BUILD ? SPL_OF_CONTROL : OF_CONTROL

Yes, this pre-reloc flag should be added.

Have the same issue with am335x boards
(http://lists.denx.de/pipermail/u-boot/2015-December/236615.html).
