[GIT PULL 1/3] ARM: defconfig: NXP LPC32xx and LPC18xx/LPC43xx changes for 5.1

[Vladimir Zapolskiy]

Hi Arnd, Olof and Kevin,

please consider to pull the updates to NXP LPC32xx and NXP LPC18xx/LPC32xx
defconfig files, both defconfigs are now up to date to provide support of
boards maintained in the Linux kernel and savedefconfig does not produce
a difference.

The following changes since commit bfeffd155283772bbe78c6a05dec7c0128ee500c:

  Linux 5.0-rc1 (2019-01-06 17:08:20 -0800)

ARM: lpc32xx: defconfig updates for v5.1

Here are the changes for ARM NXP LPC32xx and ARM NXP LPC18xx/LPC43xx
defconfig files:
* LPC18xx/LPC43xx and LPC32xx defconfig files got updates to match
  savedefconfig,
* PL11x LCD controller driver on both LPC18xx/LPC43xx and LPC32xx
  has been switched from fbdev to DRM one,
* drivers of GPIO controllers not found on LPC32xx boards are disabled,

* LPC32xx gets enabled a number of used drivers: DRM simple panel,
  fixed voltage regulator and generic SRAM drivers,
* Option to have a serial console on HS UART on LPC32xx is enabled.

[GIT PULL 2/3] ARM: dts: NXP LPC32xx and LPC18xx/LPC43xx changes for 5.1

[Vladimir Zapolskiy]

Hi Arnd, Olof and Kevin,

please consider to pull the updates to NXP LPC32xx and NXP LPC18xx/LPC32xx
board devicetree files, added support of one LPC4357 devkit board and
now proper description and usage of PL111 controller can be found on both
LPC32xx and LPC18xx/LPC43xx platforms.

The following changes since commit bfeffd155283772bbe78c6a05dec7c0128ee500c:

  tree node, this fixes a long-standing problem with its initialization,
* LPC32xx PL11x LCD controller device node got corrected properties,
  which allows to use it with a new PL11x DRM driver,
* output voltage level on one of Phytec phyCORE-LPC3250 fixed regulators
  is corrected, the fix is needed to remove duplicating platform data,
* Phytec phyCORE-LPC3250 board gets a description of a kit LCD panel,
  this completes setup of CLCD device tree node for the board,
* added unit addresses to memory device nodes on EA and Phytec boards,
* fixes of ordinary warnings in dts formatting like leading zeroes,
  unused address and size cell properties and so on.

[GIT PULL 3/3] ARM: lpc32xx: NXP LPC32xx platform changes for 5.1

[Vladimir Zapolskiy]

Hi Arnd, Olof and Kevin,

please consider to pull the updates to NXP LPC32xx platform files, the work
of moving platform data into particular board dts files has been continued.

Here are the changes for ARM NXP LPC32xx platform files:

* removed a superfluous record to kernel log buffer under OOM condition,
* use kmemdup() helper instead of kmalloc()/memcpy() pair,
* removed platform data of ARM PL180 SD/MMC and ARM PL111 LCD controllers,
  since now both are handled in devicetree files.

Nice code reduction for phy32xx!

I wonder if we ever go the pl08x DT support to the state of removing that
as well, I think Linus Walleij also looked into this in the past, but we still
seem to have this on spear, s3c64xx along with lpc32xx.

Pulled into arm/soc, thanks!

I looked into it at one point, started making patches but they became
large and scary :D but that was mostly because of SPEAr
strangeness.

The LPC32xx should be an easy conversion to DT because it does
not use custom signal handling. Are you sure it doesn't "just work"?
arch/arm/mach-lpc32xx/phy3250.c does not look like it's doing
anything the driver can't do from device tree already.

Look at:
arch/arm/boot/dts/ste-nomadik-stn8815.dtsi
for an example wikth PL08x and DMA on two UARTs.

Yours,
Linus Walleij

Pulled into arm/defconfig. It took me a bit of time to check that the refreshing
of the defconfigs did not have any side-effects that went unnoticed. It's better
to split those up further into patches that either only move around
options, or drop options with explanations of what happened.

For the newly added options, I wouldn't mind doing the reverse and enabling
everything at once with the combined changelog.

Thanks,


      Arnd
