2017-09-11ipu_common: Let the MX6 IPU clock be calculated in run-timeFabio Estevam
MX6Q/QP IPU operates at 264MHz and MX6DL IPU at 198MHz. When running a SPL target, which supports multiple MX6 variants we cannot properly setup the IPU clock frequency via CONFIG_IPUV3_CLK option as such decision is done in build-time currently. Remove the CONFIG_IPUV3_CLK option and let the IPU clock frequency be configured in run-time on mx6.

2017-09-04video: ipuv3_fb: skip IPU shutdown if IPU was not enabled beforeAnatolij Gustschin
Boards can skip display interface init using board_video_skip(). If display interface was not initialized (e.g. no ipuv3 framebuffer registered or IPU clock disabled), booting Linux stops due to the crash in IPU shutdown function, when accessing IPU registers. Check IPU clock and skip shutdown if clock is not enabled. Signed-off-by: Anatolij Gustschin <agust@denx.de>

Some toolchains fail to build "clk->rate = (u64)(clk->parent->rate * 16) / div;" And the cast usage is wrong. Use the following code to fix the issue, " do_div(parent_rate, div); clk->rate = parent_rate; " Reported-by: Peter Robinson <pbrobinson@gmail.com> Signed-off-by: Peng Fan <van.freenix@gmail.com> Cc: Stefano Babic <sbabic@denx.de> Cc: Fabio Estevam <fabio.estevam@nxp.com> Cc: Tom Rini <trini@konsulko.com> Cc: Anatolij Gustschin <agust@denx.de> Cc: Peter Robinson <pbrobinson@gmail.com> Reviewed-by: Tom Rini <trini@konsulko.com> Tested-by: Peter Robinson <pbrobinson@gmail.com>

Multiplication, as "clk->parent->rate * 16" may overflow. So use do_div to avoid such issue.

2015-04-20video, ipu: make ldb clock frequency overwritable through board codeHeiko Schocher
the ldb clock can be setup in board code (for example set through PLL5). Update the ldb_clock rate also through board code. This should be removed, if a clock framework is availiable. Signed-off-by: Heiko Schocher <hs@denx.de> Tested-by: Eric Nelson <eric.nelson@boundarydevices.com>
2015-04-20video, ipu: make ldb_clock configurableHeiko Schocher
make the ldb_clock configurable through the new define CONFIG_SYS_LDB_CLOCK. This is needed as the ldb clock is not always 650000000, for example on the aristainetos2 board, where the ldb clock derives from PLL5 clock.

2012-11-06ipu common: reset ipuv3 correctlyLiu Ying
This patch checks self-clear sw_ipu_rst bit in SCR register of SRC controller to be cleared after setting it to high to reset IPUv3. This makes sure that IPUv3 finishes sofware reset. A timeout mechanism is added to stop polling on the bit status in case the bit could not be cleared by the hardware automatically within 10 millisecond.

2010-10-22MX51: Add IPU driver for video supportStefano Babic
The patch is a porting of the IPU Linux driver developed by Freescale to have framebuffer functionalities in u-boot. The port is based on kernel 2.6.31 commit cc4fe714041805997b601fe8e5dd585d8a99297f, as delivered by Freescale [i.MX BSP]. Most features are dropped from the original driver and only LCD support is the goal of this porting. Signed-off-by: Stefano Babic <sbabic@denx.de>
