[RESEND][PATCH v3 0/6] add LCD support for SAM9X60

[Claudiu.Beznea]

From: Claudiu Beznea <claudiu.beznea@microchip.com>

Hi,

These patches adds support for SAM9X60's LCD controller.

First patches add option to specify if controller clock source is fixed.
Second patch avoid a variable initialization in atmel_hlcdc_crtc_mode_set_nofb().
The 3rd add compatibles in pwm-atmel-hlcdc driver.
The 4th patch enables sys_clk in probe since SAM9X60 needs this.
Specific support was added also in suspend/resume hooks.
The 5th patch adds SAM9X60's LCD configuration and enabled it.

I took the changes of this series and introduced also a fix
(this is the 6th patch in this series) - if you want to send it separately
I would gladly do it.

I resend this to also include Lee Jones for pwm-atmel-hlcdc changes.

Thank you,
Claudiu Beznea

Changes in v3:
- keep compatible string on patch 3/6 on a single line (I keep here a tab
  in front of ".compatible" to be aligned with the rest of the code in
  atmel_hlcdc_dt_ids[])
- patches 4/7 and 3/7 from v2 were applied so remove them from this version
- add a fix for atmel_hlcdc (patch 6/6)

Changes in v2:
- use "|" operator in patch 1/7 to set ATMEL_HLCDC_CLKSEL on cfg
- collect Acked-by, Reviewed-by tags

[RESEND][PATCH v3 1/6] drm: atmel-hlcdc: add config option for clock selection

[Claudiu.Beznea]

From: Claudiu Beznea <claudiu.beznea@microchip.com>

SAM9x60 LCD Controller has no option to select clock source as previous
controllers have. To be able to use the same driver even for this LCD
controller add a config option to know if controller supports this.

OK to add the "pwm: atmel-hlcdc: add compatible for SAM9X60 HLCDC's PWM"

Then we can add all 6 patches in one go.

Thierry suggested in v1 of this series to take pwm-atmel-hlcdc.c changes
though MFD tree [1]. Then, in v2 you ask me to do update a bit the changes
in pwm-atmel-hlcdc.c [2]. I send all the patches in one shot so that the
context to be more obvious. Sorry for the noise, if any.

Since we don't have an answer from Thierry till now, do you think it could
be feasible to take the rest of the patches in this series? After that I
will re-send the PWM patch to PWM list.

Thank you,

Thanks for the reminder.

Reworded changelog a bit in patch 6.

Sorry, you were in the original "to" list due to changes that you asked for
in v2 on mfd part.

Thierry suggested in v1 of this series to take pwm-atmel-hlcdc.c changes
though MFD tree [1]. Then, in v2 you ask me to do update a bit the changes
in pwm-atmel-hlcdc.c [2].

And in this reply I forgot to remove your email as you previously
suggested. My bad!
