* bus: ti-sysc: Fix missing reset delay handlingTony Lindgren2019-12-121-0/+4
| | | | | | | | | | | We have dts property for "ti,sysc-delay-us", and we're using it, but the wait after OCP softreset only happens if devices are probed in legacy mode. Let's add a delay after writing the OCP softreset when specified.

* bus: ti-sysc: Fix missing force mstandby quirk handlingTony Lindgren2019-12-101-1/+2
| | | | | | | | | | | | | Commit 03856e928b0e ("bus: ti-sysc: Handle mstandby quirk and use it for musb") added quirk handling for mstandby quirk but did not consider that we also need a quirk variant for SYSC_QUIRK_FORCE_MSTANDBY. We need to use forced idle mode for both SYSC_QUIRK_SWSUP_MSTANDBY and SYSC_QUIRK_FORCE_MSTANDBY, but SYSC_QUIRK_SWSUP_MSTANDBY also need to additionally also configure no-idle mode when enabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementation for ti-sysc powers down the module once module init is complete. However, right after power is disabled, it is enabled via runtime PM. This is unnecessary so avoid it by re-ordering the events a bit; move powering down of the module post runtime PM enable which makes sure the use counts are maintained properly and there is no extra power down/up sequence for the module.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There seems to be unnecessary extra hardreset line toggling applied during module init. This is unnecessary, as the reset lines are already asserted during boot, and it can cause certain modules to hang (iommus, remoteprocs.)

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main clocks and reset controls have a hardware level dependency, where one can't transition state without the other one transitioning. Because we don't have the dependency implemented in software, we must ensure the ordering of these two is done properly; they way this is handled is that clocks transition on software level without delay, and the status is only polled on reset side. Because of this, we must re-order the main clock and reset handling on the ti-sysc driver. Signed-off-by: Tero Kristo <t-kristo@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

On am3 and am4 we need to also set swsup quirk flag I probably only tested this earlier with watchdog service running when the watchdog never gets disabled.

But it also caused unpaired clockdomain calls that won't allow idling the system. That's because clkdm_allow_idle_nolock() and clkdm_deny_idle_nolock() have usage count with clkdm->forcewake_count. Let's drop the unpaired sysc_clkdm_deny_idle() to fix idling of devices.

Let's fix the issue by always enabling clocks init, and never disable them for "ti,no-idle" quirk.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the size_t variable res is being checked for an error failure however the unsigned variable is never less than zero so this test is always false. Fix this by making variable res ssize_t Link: https://lore.kernel.org/r/20190822010351.15660-2-marek.behun@nic.cz Addresses-Coverity: ("Unsigned compared against 0") Fixes: 5bc7f990cd98 ("bus: Add support for Moxtet bus") Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Marek Behún <marek.behun@nic.cz> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Switch from module_platform_driver_probe() to module_platform_driver(). The former is not suitable for booting with device tree as the driver will be registered before the device and thus won't be probed again when the device is present.
