2019-03-28sunxi: video: HDMI: Fix clock setupJernej Skrabec
Currently, HDMI driver doesn't consider minimum and maximum allowed rate of pll3 (video PLL). It works most of the time, but not always. Consider monitor with resolution 1920x1200, which has pixel clock rate of 154 MHz. Current code would determine that pll3 rate has to be set to 154 MHz. However, minimum supported rate is 192 MHz. In this case video output just won't work. The reason why the driver is written in the way it is, is that at the time HDMI PHY and clock configuration wasn't fully understood. But now we have needed knowledge, so the issue can be fixed. With this fix, clock configuration routine uses full range (1-16) for clock divider instead of limited one (1, 2, 4, 11). It also considers minimum and maximum allowed rate for pll3.

The "old" bmp command did support this operartion mode and to not break compatibility with the move to DM_VIDEO, we need to add this support to the "new" bmp code.

Current EDID detailed timing parser errors out when either horizontal or vertical pulse sync width is 0, thus not allowing a display with EDID listed below work properly. EDID below works ok within Linux although it warns about these two fields being 0. Therefore relax the checks a bit so we can actually use this the screen out of the box.

2018-11-14video: simplefb: Remove DM_FLAG_PRE_RELOC flagBin Meng
When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be bound before relocation. However due to a bug in the DM core, the flag only takes effect when devices are statically declared via U_BOOT_DEVICE(). This bug has been fixed recently by commit "dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()", but with the fix, it has a side effect that all existing drivers that declared DM_FLAG_PRE_RELOC flag will be bound before relocation now. This may expose potential boot failure on some boards due to insufficient memory during the pre-relocation stage. To mitigate this potential impact, the following changes are implemented: - Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver only supports configuration from device tree (OF_CONTROL) - Keep DM_FLAG_PRE_RELOC flag in the driver only if the device is statically declared via U_BOOT_DEVICE() - Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for drivers that support both statically declared devices and configuration from device tree Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
