It is mostly the same SOC except for, at least, one clock tree which is different. This difference is only known by looking at the BSP kernel [1]. Currently, the mainline kernel will not hang on rk3288w but it is probably by "chance" because we got an issue on a lower kernel version. According to Rockchip's U-Boot [2], the rk3288w can be detected using the HDMI revision number (= 0x1A) in this version of the SOC. Changelog --------- This V4 is pretty much the same than the V3. Added the dt-bindings documentation in clock-controller dt-bindings and fixed some typos according to Heiko's reviews. Changes since v3: - Updated clock-controller's dt-bindings - Fixed indentation Best regards, Mylène Josserand [1] https://github.com/rockchip-linux/kernel/blob/develop-4.4/drivers/clk/rockchip/clk-rk3288.c#L960..L964 [2] https://github.com/rockchip-linux/u-boot/blob/next-dev/arch/arm/mach-rockchip/rk3288/rk3288.c#L378..L388 Mylène Josserand (2): clk: rockchip: rk3288: Handle clock tree for rk3288w dt-bindings: clocks: rk3288: add possible rk3288w .../bindings/clock/rockchip,rk3288-cru.txt | 8 +++++++- drivers/clk/rockchip/clk-rk3288.c | 20 +++++++++++++++++-- 2 files changed, 25 insertions(+), 3 deletions(-)
