Hi all, The Samsung Exynos eDP controller and Rockchip RK3288 eDP controller share the same IP, so a lot of parts can be re-used. I split the common code into bridge directory, then rk3288 and exynos only need to keep some platform code. Cause I can't find the exact IP name of exynos dp controller, so I decide to name dp core driver with "analogix" which I find in rk3288 eDP TRM ;)
Beyond that, there are three light registers setting differents bewteen exynos and rk3288. 1. RK3288 have five special pll resigters which not indicata in exynos dp controller. 2. The address of DP_PHY_PD(dp phy power manager register) are different between rk3288 and exynos. 3. Rk3288 and exynos have different setting with AUX_HW_RETRY_CTL(dp debug register).
My series patches can be divider into two parts: One for spliting the analogix_dp code from exynos dp driver. Another are trying to add rk3288 platform special code.
Thanks, - Yakir
Changes in v2: - Take Joe Preches advise, improved commit message more readable, and avoid using some uncommon style like bellow: - retval = exynos_dp_read_bytes_from_i2c(... ...) + retval = + exynos_dp_read_bytes_from_i2c(......); - Take Jingoo Han suggest, cause I jsut improve parts of the code, so just remove my name from author list. - Take Jingoo Han suggest, remove new copyright - Fix compiled failed dut to analogix_dp_device misspell - Add GNU license v2 declared and samsung copyright - Fix compile failed dut to phy_pd_addr variable misspell error
