* ARM: i.MX: Move mach header files to include/mach/imxSascha Hauer2023-03-061-7/+7
| | | | | | | | | | | Currently arch specific headers can be included with #include <mach/xxx.h>. With upcoming multi-arch support this is no longer possible as there won't be a single mach anymore. Move all i.MX specific header files to include/mach/imx/ to prepare for multi-arch support. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: i.MX: romapi: Hide using NULL pointers from gcc #2Sascha Hauer2022-11-231-0/+2
| | | | | | | | | | | The i.MX ROM API lies in the NULL page. Accessing that results in compiler warnings like: include/asm-generic/io.h:27:51: warning: array subscript 0 is outside array bounds of 'volatile unsigned char[0]' [-Warray-bounds] Use OPTIMIZER_HIDE_VAR() to hide using NULL pointers from the compiler.

* ARM: i.MX: Reset OTG controller during startupSascha Hauer2018-09-041-0/+4
| | | | | | | | | | | | | | | | When booting from USB it's sometimes observed that the USB stack on the remote host gets confused. This happens when we adjust the PLLs the USB controller is hanging on. The ROM just leaves the USB controller enabled when it passes control to the bootloader, so in case the usb clks are enabled make sure we reset the otg before doing any critical clock operations. This is currently done for i.MX50, i.MX51, i.MX53 and i.MX6, but a similar thing can happen on other i.MXes aswell.

* ARM: i.MX53: do not pass base address to imx*_boot_save_locSascha Hauer2016-09-221-1/+1

* ARM: i.MX: move esdctl device registration to soc_initSascha Hauer2013-08-201-1/+1
| | | | | | | | | The esdctl devices are currently not in the devicetrees. this means they are not registered when booting from the devicetree. Move the device registration from soc_devices_init to soc_init which is called even with devicetree support so that we get esdctl devices. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: i.MX: centralize i.MX startupSascha Hauer2013-06-241-2/+6
| | | | | | | Each i.MX SoC has its own SoC initcall. To ease multi SoC support move it to a single initcall. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: i.MX53: split lowlevel function into early/nonearly versionSascha Hauer2013-04-051-4/+8
| | | | | | | | | clock_notifier_call_chain() can't be called before init time. Protecting it with IS_ENABLED(__PBL__) is not enough. This patch splits out a new imx53_init_lowlevel_early which can be called before init time and does not have the call to clock_notifier_call_chain() in it.

* ARM: i.MX53: Fix pll216 setupSascha Hauer2013-04-041-1/+1
| | | | | | | | The value for i.MX53 216MHz is actually 432MHz. Use the same value as for i.MX51 which really corresponds to 216MHz. These are the same PLL216 values as U-Boot uses. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM i.MX53: enable imx53_init_lowlevel for pblSascha Hauer2012-10-171-1/+3
| | | | | | | | | The KARO Tx53 board in the revision 8030 has an instable SDRAM setup. It works as long as the MMU is disabled, but the board crashes at arbitrary places once the MMU gets enabled. So we need the PLL setup early. Enable it for pbl. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | Rather than doing this in the SoC specific code just print it in imx_set_silicon_revision. This saves some lines of code and also results in i.MX27 now also having the silicon revision printed during startup. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM i.MX53: notify clocksource about changing clockWjatscheslaw Stoljarski (Slawa)2012-07-251-0/+2
| | | | | | | | | | | | This fix a clock inaccuracy in get_time_ns (used by sleep, time, etc). At i.MX53 power-on GPT clock is typically 55500000 Hz, and it will be used to calc the clock multiplier. After call imx53_init_lowlevel() GPT clock will changed (e.g. to 66666666 Hz), but multiplier not. To fix this behavior call clock_notifier_call_chain() after changing clock in imx53_init_lowlevel().

* ARM i.MX53: Add lowlevel init codeSascha Hauer2011-10-131-0/+147
| | | | | | | | | | | | | This adds lowlevel (AIPS, PLL, L2) initialization for i.MX53 boards. This is a direct transcription of Freescales U-Boot assembler code with the exception that we initialize PLL1 with 1000MHz and assume that all necessary voltages are already adjusted when we arrive here. It must be explicitely called from the boards so a board is free to do it's own initialization. However, boards should use this code and make it more configurable if necessary.
