This change includes below - 1. For T23x, CEC engine is moved to AON partition. As AON partition does not powergate, skip all powergate/unpowergate calls for t23x. 2. The clock on which CEC engine operates, 32k/rtc_clk, it is always running clock in AON partition. So skip clock enable/disable APIs. 3. This change also skips calls to TEGRA DC engine which is not available from T23x. 4. RX Buffer size is increased to 64 depth from 1 depth. So new register is provided to program depth so that interrupt gets triggered when certain depth is filled. By default it is 64 depth so program it to 1 depth to match old behavior. 5. When tegradc is absent, read physical address from SPARE register which will be populated by UEFI. 6. This change also adds new register definitions in header file which needs to program when adding support for CEC SC7 wakeup. 7. Timing registers updated for T23x as per HW guidelines. 8. Some initialization code is changed for T23x. 9. Add devicetree binding documentation. bug 200727002 Change-Id: I71c2d323632c61e4c4b82bcdbca9e72179761224 Signed-off-by: Prafull Suryawanshi <prafulls@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nvidia/+/2523595 Tested-by: mobile promotions <svcmobile_promotions@nvidia.com> Reviewed-by: svc_kernel_abi <svc_kernel_abi@nvidia.com> Reviewed-by: Shu Zhong <shuz@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> GVS: Gerrit_Virtual_Submit
