imx6: clock: allow different clock sources for ldb

2026-06-27T02:02:46Z

The LDB clock sources don't have to be the same, so allow DI1 clock to be configured separately. Unlikely to be significant, but the reason will become apparent in the following commit. Signed-off-by: Brian Ruley

imx6: clock: add support to get LCD pixel clock rate

2023-05-02T08:57:32Z

Add the get_lcd_clk() function to get the LCD pixel clock rate. The patch has been tested on imx6ul platform. Signed-off-by: Dario Binacchi

command: Remove the cmd_tbl_t typedef

2020-05-18T22:36:55Z

We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass

arm: Don't include common.h in header files

2020-05-18T18:54:24Z

It is bad practice to include common.h in other header files since it can bring in any number of superfluous definitions. It implies that some C files don't include it and thus may be missing CONFIG options that are set up by that file. The C files should include these themselves. Update some header files in arch/arm to drop this. Signed-off-by: Simon Glass

mx6: clock: Introduce disable_ipu_clock()

2019-11-03T12:16:51Z

Introduce disable_ipu_clock(). This is done in preparation for configuring the NoC registers on i.MX6QP in SPL. Afer the NoC registers are set the IPU clocks can be disabled. Signed-off-by: Fabio Estevam Reviewed-by: Peng Fan

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

mx6: clock: Add a prototype for do_mx6_showclocks()

2017-10-12T16:00:01Z

When compiling with W=1 the following warning is observed: arch/arm/mach-imx/mx6/clock.c:1268:5: warning: no previous prototype for ‘do_mx6_showclocks’ [-Wmissing-prototypes] int do_mx6_showclocks(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[]) Remove this warning by adding the function prototype into arch-mx6/clock.h file.

imx: clock: gate clk before changing pix clk mux

2016-12-16T10:38:24Z

The LCDIF Pixel clock mux is not glitchless, so need to gate before changing mux. Also change enable_lcdif_clock prototype with a new input parameter to indicate disable or enable. Signed-off-by: Peng Fan Cc: Stefano Babic

imx6: clock: Enable External Memory Interface [EIM] clock (eim_slow_clock)

2016-11-30T08:57:19Z

This patch extends the imx6 clock code to enable or disable the EIM slow clock, which in necessary when one wants to use EIM interface t o read/write from external memory (e.g. NOR). Signed-off-by: Lukasz Majewski

imx: mx6: Fix procedure to switch the parent of LDB_DI_CLK

2016-04-19T14:05:12Z

Due to incorrect placement of the clock gate cell in the ldb_di[x]_clk tree, the glitchy parent mux of ldb_di[x]_clk can cause a glitch to enter the ldb_di_ipu_div divider. If the divider gets locked up, no ldb_di[x]_clk is generated, and the LVDS display will hang when the ipu_di_clk is sourced from ldb_di_clk. To fix the problem, both the new and current parent of the ldb_di_clk should be disabled before the switch. This patch ensures that correct steps are followed when ldb_di_clk parent is switched in the beginning of boot. This patch was ported from the 3.10.17 NXP kernel http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/commit/?h=imx_3.10.17_1.0.1_ga&id=eecbe9a52587cf9eec30132fb9b8a6761f3a1e6d NXP errata number: ERR009219, EB821 Signed-off-by: Akshay Bhat Cc: Stefano Babic Cc: Fabio Estevam
