Also fixes for ti81x booting and revision check updates. These are based on omap-for-v3.11/soc-signed because of the am43x dependency to earlier patches. * tag 'omap-for-v3.11/soc-part2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP3+: am33xx id: Add new am33xx specific function to check dev_feature ARM: OMAP: TI816X: add powerdomains for TI816x ARM: OMAP2: TI81XX: id: Add cpu id for TI816x ES2.0 and ES2.1 ARM: OMAP2+: AM43x: basic dt support Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2013-06-17ARM: OMAP2+: Powerdomain: Remove the need to always have a voltdm associated ↵Rajendra Nayak
to a pwrdm The powerdomain framework currently expects all powerdomains to be associated with a corresponding voltagedomain. For some SoCs' (like the already existing AM33xx family, or for the upcoming AM437x and DRA7 SoCs') which do not have a Voltage controller/Voltage Processor (neither the SR I2C bus to communicate with the PMIC) there is no need for a Powerdomain to have a voltage domain association since there is no auto-scaling of voltages possible using the voltage FSM. Extend the arch operations to add an api which the powerdomain core can then use to identify if a voltdm lookup and association for a powerdomain is really needed.

Enable MMC_UNSAFE_RESUME to be accomplish a proper suspend/resume cycle for SD/SDIO/(e)MMC. ARMMMCI host driver supports clock gating through runtime PM, thus MMC_CLKGATE is not needed. Moreover ARMMMCI can do scatter-gather which means we can explicity disable MMC_BLOCK_BOUNCE, since it's default enabled, to skip unnecessary bounce buffer copying.

2013-06-17spi: pl022: use DMA by default when probing from DTLinus Walleij
In the past we controlled the selection of DMA for a certain host by a boolean switch in the platform data. Currently there is no way to enable DMA on a PL022 probed from the device tree. Let's default to trying to obtain DMA channels in the DT case, and then we can always fail (and thus fall back to PIO mode). Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
