We already support exynos5420 in the mainline. It only slightly differs from Exynos5422. Additionally there is Exynos5800 which is a different HW revision of Exynos5422.
Yes. You're right. I was not in the subscriber list when I send this mail. So when I sent this mail, I received an auto-replied mail which I can cancel this email. I canceled this mail. But the mail sent to your and Minkyu Kang was not. Sorry for the confusion. Please refer the latest mail.
Ok.
Probably by a mistake, I've received this series three times :-).
When you prepare v2, please add change log and cover letter.
In the message topic you stated that you add support for Exynos5422. Maybe we could use Exynos5800 name also for Exynos5422 (with a big, fat note about those two chips compliance added to ./doc directory)?
@ Akshay, Minkyu:
What do you think about this idea?
Best regards, Hyungwon Hwang
