[PATCH 0/3] Davinci support for EHRPWM & ECAP

[PATCH 0/3] Davinci support for EHRPWM & ECAP

[Philip Avinash]

This patch series enables EHRPWM & ECAP driver support for da850
platforms.

This patch series based on [1] and is available at [2]. This has been tested
backlight support using EHRPWM in da850-evm.

[PATCH 1/3] pwm: davinci: Add Kconfig support for ECAP & EHRPWM devices

[Philip Avinash]

Add EHRPWM and ECAP support build support for DAVINCI_DA850 platforms.

Also, since DAVINCI platforms doesn't support TI-PWM-Subsystem module,
remove the select option for CONFIG_PWM_TIPWMSS.

Also, update CONFIG_PWM_TIPWMSS compiler directive appropriately in
pwm-tipwmss.h to fix the below compiler error upon removal of
CONFIG_PWM_TIPWMSS for Davinci platforms.

Having such narrow dependencies is wrong. The same device is present on
DaVinci DA830 too. A depends on should not be required at all since the
driver should build on all architectures. But I have seen resistance to
doing that since users don't like to see configuration options totally
irrelevant for the architecture they are building for. So may be take a
middle path and do 'depends on ARCH_ARM'?

Thanks,

Perhaps SOC_AM33XX || ARCH_DAVINCI_DA8XX would be an alternative?

You add a new compatible, but don't really show any changes in driver in
this series. So why can't we simply use ti,am33xx-ecap on DA850 too?

You add a new compatible, but don't really show any changes in driver in
this series. So why can't we simply use ti,am33xx-ecap on DA850 too?

Ok it can happily live with ti,am33xx-ecap. Hence this patch and next [1]patch

Indeed, if the hardware block is identical the dts should simply list:

compatible = "ti,da850-ecap", "ti,am33xx-ecap"

And the driver only bind to ti,am33xx-ecap (unless there ever needs to
be a da850 specific workarounde.

[PATCH 3/3] pwm: pwm-tiehrpwm: Add device tree binding support for da850 SOC

[Philip Avinash]

EHRPWM IP is used in da850 SOC's also. Hence adds EHRPWM device tree
binding support for da850.
