Hi,
This series adds DT support to da8xx-fb driver (device found on
DaVinci and AM335x SoC's). It does certain cleanup's in the process.
This series as compared to previous version handles configuration of
the LCDC input clock to required value if clock divider in IP cannot
take care of required pixel clock. In the case of AM335x (where there
is requirement of configuring input clock), it's clock tree has to be
updated with proper flags, relevant patch is,
"ARM: AM33XX: clock: SET_RATE_PARENT in lcd path".
There is an additional patch in this new series to make io operations
safe.
This makes use of Steffen Trumtrar's v16 of display timing DT support.
Testing has been done on AM335x SoC based boards like AM335x EVM and
AM335x EVM-SK. It has also been verified that display on DA850 EVM
(non-DT boot) works as earlier.
This series is based on v3.8-rc3,
and is dependent on,
1. Series v16 "of: add display helper" by,
Steffen Trumtrar <s.trumtrar@xxxxxxxxxxxxxx>
2. Patch "da8xx: Allow use by am33xx based devices" by,
Pantelis Antoniou <panto@xxxxxxxxxxxxxxxxxxxxxxx>
3. Series v3 "video: da8xx-fb: runtime timing configuration" by,
me (Afzal Mohammed <afzal@xxxxxx>)
To test this series on AM335x based boards,
1. Series v2 "ARM: dts: AM33XX: lcdc support" by,
me (Afzal Mohammed <afzal@xxxxxx>),
2. Patch "ARM: AM33XX: clock: SET_RATE_PARENT in lcd path" by,
me (Afzal Mohammed <afzal@xxxxxx>),
3. Series "HWMOD fixes for AM33xx PWM submodules and device tree nodes" by,
Philip, Avinash <avinashphilip@xxxxxx>
would be needed.
All above dependencies along with those required for testing is available

Afzal
