This series adds support for DVB Frontend system named HSC support
for UniPhier LD11/LD20 SoCs. This driver supports MPEG2-TS serial
signal input from external demodulator and DMA MPEG2-TS stream data
onto memory.
UniPhier HSC driver provides many ports of TS input. Since the HSC
has mixed register map for those ports. It hard to split each register
areas.

This file name is strange.
A comma should be used a separator between a vendor name and a device name.
The "uniphier" is not a vendor name.

What's the point of adding an empty Makefile,
and header files in a separate commit?
Anyway, ...

Not so sure if regmap is useful here.
Anyway this driver uses regmap_{read,write},
but 'select REGMAP_MMIO' is missing.

This is OK.
The members of enum should be capitalized.

Why is this block comment sylte?
Documentation/process/coding-style.rst says
this style is used only files under net/ and drivers/net.

CDMBC_CHTDCTRLH(i) was a macro,
but HSC_INT() is a static inline function inconsistently,
then used from the lots of macros below...
Wow.
This is already enough crap.
Is there any other way instead of
putting all the mess into registers?

Look like each must have a particular value.
Is it important to HSC_CSS_IN_TSO0 == 0x18 ?
If so, it might be better to do
#define HSC_CSS_IN_TSO0 0x18

Suspicious usage of 'const'
since ucode_spu is not a pointer.
Look like you constified the whole hsc_spec,
so this 'const' should be here.

Ditto.

OK, this 'const' is legitimate since init-rams a pointer.

A good thing of <linux/bitfield.h> is, it is compile-time computable,
but this is not.
It might be better to re-consider the hsc_spec_css_out data arrangement.
For example, shift & width pair instead of shifted-mask.

What's the point of adding an empty Makefile,
and header files in a separate commit?
Anyway, ...

Not so sure if regmap is useful here.
Anyway this driver uses regmap_{read,write},
but 'select REGMAP_MMIO' is missing.

Why is this block comment sylte?
Documentation/process/coding-style.rst says
this style is used only files under net/ and drivers/net.

CDMBC_CHTDCTRLH(i) was a macro,
but HSC_INT() is a static inline function inconsistently,
then used from the lots of macros below...
Wow.
This is already enough crap.
Is there any other way instead of
putting all the mess into registers?

Look like each must have a particular value.
Is it important to HSC_CSS_IN_TSO0 == 0x18 ?
If so, it might be better to do

Suspicious usage of 'const'
since ucode_spu is not a pointer.
Look like you constified the whole hsc_spec,
so this 'const' should be here.

Ditto.

OK, this 'const' is legitimate since init-rams a pointer.

A good thing of <linux/bitfield.h> is, it is compile-time computable,
but this is not.
It might be better to re-consider the hsc_spec_css_out data arrangement.
For example, shift & width pair instead of shifted-mask.

This patch adds submodules of HSC for UniPhier SoCs.
These work as follows:
ucode: Load uCode and start subsystems
css : Switch stream path
ts : Receive MPEG2-TS clock and signal
dma : Transfer MPEG2-TS data bytes to main memory

To: linux-arm-kernel
This patch adds submodules of HSC for UniPhier SoCs.
These work as follows:
ucode: Load uCode and start subsystems
css : Switch stream path
ts : Receive MPEG2-TS clock and signal
dma : Transfer MPEG2-TS data bytes to main memory

If you claim this driver is tristate,
you need to do compile-test with =m.

This patch adds common module for UniPhier DVB adapter drivers

Please add $(srctree)/ like
ccflags-y += -I$(srctree)/drivers/media/dvb-frontends/
ccflags-y += -I$(srctree)/drivers/media/tuners/
Currently, it works $(srctree)/,
but I really want to rip off the build system hack.

Thanks, I agree with your opinion, but other Makefiles in drivers/media use
same hack. I don't know other way to include headers of demodulators and
tuners...
Do you have any good ideas?

Thanks, I agree with your opinion, but other Makefiles in drivers/media use
same hack. I don't know other way to include headers of demodulators and
tuners...
Do you have any good ideas?

My suggestion is to add '$(srctree)/'.
For clarification,
Bad:
ccflags-y += -Idrivers/media/dvb-frontends/
ccflags-y += -Idrivers/media/tuners/
Good:
ccflags-y += -I$(srctree)/drivers/media/dvb-frontends/
ccflags-y += -I$(srctree)/drivers/media/tuners/
I want to fix this tree-wide,
then remove the 'addtree' from scripts/Kbuild.include
but I have not been able to find time for that.
This is a new file, so just suggested to add '$(srctree)/'

This is weird.
>From drivers/media/platform/uniphier/Makefile,
obviously you link all the objects into the single module, uniphier-dvb.ko
It contains zero, one, or two sets of MODULE_* depending on CONFIG options.
- Zero MODULE_LICENSE / MODULE_AUTHOR / MODULE_DESCRIPTION
if CONFIG_DVB_UNIPHIER_LD11_ISDB=n &&
CONFIG_DVB_UNIPHIER_LD20_ISDB=n
- Two sets of MODULE_LICENSE / MODULE_AUTHOR / MODULE_DESCRIPTION
if CONFIG_DVB_UNIPHIER_LD11_ISDB=y &&
CONFIG_DVB_UNIPHIER_LD20_ISDB=y
What you can do is:
- Split the module into core, ld11, ld20
or
- Move the module tags and entry to hsc-core.c
and leave only the data arrays in ld11, ld20.
