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 goes back to v2 way of
configuring pixel clock rate. i.e. set divider if rate is within
the range that is configurable with existing input clock rate, else
change input clock rate as required instead of modeling CCF clock
nodes in the driver (more details in 12/12)
This makes use of Steffen Trumtrar's v17 of display timing DT support.
Testing has been done on AM335x SoC based boards like AM335x EVM. 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 v17 "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 "HWMOD fixes for AM33xx PWM submodules and device tree nodes" by,
Philip, Avinash <avinashphilip@xxxxxx>
as well as following,
2. Series v2 "ARM: dts: AM33XX: lcdc support",
3. Patch v2 "ARM: OMAP2+: dpll: am335x - avoid freqsel",
4. Patch v2 "ARM: OMAP2+: clock: DEFINE_STRUCT_CLK_FLAGS helper",
5. Patch v2 "ARM: AM33XX: clock: SET_RATE_PARENT in lcd path" by,
me (Afzal Mohammed <afzal@xxxxxx>)
would be needed.
All above dependencies along with those required for testing is available

v5: use v2 method of configuring pixel clock rate instead of modeling
CCF clock nodes in driver, i.e. set divider if rate is within
the range that is configurable with existing input clock rate,
else change input clock rate as required.
v4: use new registration for clock divider having minimum divider
requirement and have ifdef'ery in a better way
v3: model CCF clock divider with parent propogation if CCF selected
v2: 2 new patches - one to configure clock rate properly (12/12)and
other to make io operations safe (1/12)
Afzal Mohammed (11):
video: da8xx-fb: make io operations safe
video: da8xx-fb: enable sync lost intr for v2 ip
video: da8xx-fb: use devres
video: da8xx-fb: ensure non-null cfg in pdata
video: da8xx-fb: reorganize panel detection
video: da8xx-fb: minimal dt support
video: da8xx-fb: invoke platform callback safely
video: da8xx-fb: obtain fb_videomode info from dt
video: da8xx-fb: ensure pdata only for non-dt
video: da8xx-fb: setup struct lcd_ctrl_config for dt
video: da8xx-fb: set upstream clock rate (if reqd)
