2014-12-26ARM: pxa: add regulator_has_full_constraints to spitz board fileDmitry Eremin-Solenikov1-0/+2
Add regulator_has_full_constraints() call to spitz board file to let regulator core know that we do not have any additional regulators left. This lets it substitute unprovided regulators with dummy ones. This fixes the following warnings that can be seen on spitz if regulators are enabled: ads7846 spi2.0: unable to get regulator: -517 spi spi2.0: Driver ads7846 requests probe deferral Cc: stable@vger.kernel.org Signed-off-by: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com> Acked-by: Mark Brown <broonie@kernel.org> Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>

The em_x270_mci_setpower() and em_x270_usb_hub_init() functions call regulator_enable(), which may return an error that must be checked. This changes the em_x270_usb_hub_init() function to bail out if it fails, and changes the pxamci_platform_data->setpower callback so that the a failed em_x270_mci_setpower call can be propagated by the pxamci driver into the mmc core.

2012-12-24ARM: delete struct sys_timerStephen Warren1-3/+3
Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

For some platforms, it is inappropriate to register all PXA UARTs. In some cases, the UARTs may not be used, and in others we may want to avoid registering the UARTs to allow other drivers (eg, FICP) to make use of the UART. In addition, a while back there was a request to be able to pass platform data to the UART driver.
