[PATCH 0/2] gpio: davinci: reuse for keystone arch

[PATCH 0/2] gpio: davinci: reuse for keystone arch

[Grygorii Strashko]

This series is intended to update Davinci GPIO driver and reuse
it for Keystone SoCs, because Keystone uses the similar GPIO IP like Davinci.
Keystone GPIO IP: supports:
- up to 32 GPIO lines;
- only unbanked irqs;

See Documentation:
Keystone - http://www.ti.com/lit/ug/sprugv1/sprugv1.pdf

This series depends on:
[1] "[PATCH 1/2] gpio: davinci: Fix a check for unbanked gpio"
https://lkml.org/lkml/2013/11/8/22
[2] "[PATCH v6 0/6] gpio: daVinci: cleanup and feature enhancement"
https://www.mail-archive.com/devicetree at vger.kernel.org/msg05970.html
[3] "gpio: davinci: get rid of DAVINCI_N_GPIO"
https://lkml.org/lkml/2013/11/26/405
[4] "gpio: introduce GPIO_DAVINCI kconfig option"
https://lkml.org/lkml/2013/11/26/435
[5] "gpio: davinci: use chained_irq_enter/chained_irq_exit API"
https://lkml.org/lkml/2013/11/26/428

To handle all dependencies, I've created a branch where I collected all 
"ready to merge" patches (all acks added in patches) and this series:
- https://github.com/grygoriyS/linux.git
- branch: keystone-master-gpio-for-next

The "keystone-master-gpio-for-next" based on:
 https://git.kernel.org/cgit/linux/kernel/git/ssantosh/linux-keystone.git
 branch: keystone/master

[PATCH 1/2] gpio: davinci: don't create irq_domain in case of unbanked irqs

[Grygorii Strashko]

The system may crash if:
- there are more then 1 bank
- unbanked irqs are enabled
- someone will call gpio_to_irq() for GPIO from bank2 or above

Hence, fix it by not creating irq_domain if unbanked irqs are enabled
and correct gpio_to_irq_banked() to handle this properly.

[PATCH 2/2] gpio: davinci: reuse for Keystone SoC

[Grygorii Strashko]

The similar GPIO HW block is used by keystone SoCs as
in Davinci SoCs.
Hence, reuse Davinci GPIO driver for Keystone taking into
account that Keystone contains ARM GIC IRQ controller which
is implemented using IRQ Chip.

According to the other renamings I see in this file, shouldn't the

So you want to have a generic name here. If you are changing it, change it
across the driver in a separate patch or leave it as is...
I don't think it matters much..

With those comments addressed, you can add my ack.

Can one of you pull all these patches ?

If needed I can take these patches to arm-soc with Linus's ack
or can prepare a pull request which Linus W can pull from from.

So I went through my backlog and queued all that I think is ready. Here
is the branch. Let me know if there is anything else missing.

Forgot to mention that I have not been able to test them today though.
They will hit linux-next only after I have been able to test them and I
send a pull request to arm-soc or Linus W.
