SubjectRe: [PATCH v2 00/11] Rockchip ISP1 Driver
HI all,

2017-11-24 10:36 GMT+08:00 Jacob Chen <jacob-chen@iotwrt.com>:
> This patch series add a ISP(Camera) v4l2 driver for rockchip rk3288/rk3399 SoC.

Sorry, i forget to add a changelog.

changes in V2:
mipi-phy:
- use async probing
- make it be a child device of the GRF

isp:
- add dummy buffer
- change the way to get bus configuration, which make it possible to
add parallel sensor support in the future(without mipi-phy driver).


I resend it for now because i think v2 patch looks more clearly than
the old one,
the v1 patch could just be superseded.
