* video: imxfb: make pcr and bpp per-display settingsUwe Kleine-König2019-09-121-7/+3
| | | | | | | | | | | | These settings used to be specified per-mode. But the device tree bindings have these two values attached to the display and not to each mode. Also for the supported boards it doesn't matter as they all only have a single mode. This is preparatory work to add devicetree support for the imxfb driver.

| * reset_source: drop reset_source_set_instance()Uwe Kleine-König2019-08-281-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | The semantic of reset_source_set_instance() required a separate call to reset_source_set() (or reset_source_set_priority()) and checked right usage only using the type. Make the set of functions a bit easier to use by dropping reset_source_set_instance() and instead introduce a function that can set all relevant parameters (source, priority and instance) in one go.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When only a single i.MX SoC is selected the cpu_is_mx?() macros expand to static 0 or 1. With the generic DT image enabled it could be though that the SoC is not a i.MX at all, so make sure that with the generic DT image enabled the cpu_is_mx?() macros always compare against __imx_cpu_type Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The generic DT image built with CONFIG_ARCH_IMX has nothing really i.MX specific except that it has support for i.MX features. The DT image could be started with a non i.MX device tree which works as expected. imx_init() panics though when started with a non i.MX device tree. Remove the hang() so that we can just continue.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far, writing a barebox image exceeding the partition size aborts with EPERM as truncate isn't implemented: ERROR: writing to /dev/flash-boot.barebox failed with Operation not permitted update failed ERROR: fastboot: update barebox: Operation not permitted This is unfortunate because by the time the truncation fails, erasing the partition had already occurred. Avoid this by checking prior to the pwrite_all whether the file to be written is big enough. This is valid here because barebox update wouldn't be called on a regular file. While at it, present callers with a more helpful ENOSPC error. Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | pinctrl: i.MX iomux-v1: Make base address initialization unnecessarySascha Hauer2019-08-144-7/+20
|/ | | | | | | | | | | | So far we have imx_gpio_mode() to configure a pinmux entry for the older i.MX pinmuxes. For this to work imx_iomuxv1_init() must be called beforehand to configure the base address. Simplify this by introducing SoC specific variants of imx_gpio_mode() which also pass the base address. This makes initialization of the base address unnecessary and the functions usable for PBL. Consequently also compile the code for PBL. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

The original intent was most probably to add an exception for the i.MX6 Solo as well, so everything else is skipped, including the SX, SL and now the UL and ULL. Fix the code to reflect this. On the SX, SL, UL, ULL, this now avoids writes to memory, which isn't described in the datasheets. On the S, it now configures the QoS settings.

| * | ARM: i.MX8MQ: Don't use cpu_is_mx8mq() at core_initcall levelAndrey Smirnov2019-03-183-22/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since __imx_cpu_type won't be initialized until imx_init()@postcore_initcall is executed cpu_is_mx8mq() will only work correctly at core_initcall level so long as imx_cpu_type does not resolve into __imx_cpu_type. This is currently the case and imx8mq_init_syscnt_frequency() works as expected, but it probably won't be in the future. To avoid this problem introduce imx8mq_cpu_lowlevel_init() and do system counter frequency initialization there. Also convert all of the i.MX8MQ boards to use this new function.

| * | ARM: i.MX7: Make sure CNTFRQ is initialized early enoughAndrey Smirnov2019-03-182-35/+13
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to make sure that CNTFRQ is initialized before corresponding clocksource driver tries to use it, otherwise we'll end up crashing due to division by zero. We can't convert imx7_timer_init() to be an initcall since it is an i.MX7 specific task, but CPU type information won't be availible until after imx_init() gets executed at postcore_initcall() level. To solve this move all of the necessary code to be a part of imx7_cpu_lowlevel_init(). Note, that original code both hardcoded frequency value to 8MHz as well as tried to write it to the first element of the frequency mode table which appears to be read-only on i.MX7. So while we are at it, simplify the code by adding set_cntfrq() implementation for ARMv7 and copy the code we already using for i.MX8MQ.
