SPEAr3xx architecture includes shared/multiplexed irqs for certain set of devices. The multiplexor provides a single interrupt to parent interrupt controller (VIC) on behalf of a group of devices. There can be multiple groups available on SPEAr3xx variants but not exceeding 4. The number of devices in a group can differ, further they may share same set of status/mask registers spanning across different bit masks. Also in some cases the group may not have enable or other registers. This makes software little complex. Present implementation was non-DT and had few complex data structures to decipher banks, number of irqs supported, mask and registers involved. This patch simplifies the overall design and convert it in to DT. It also removes all registration from individual SoC files and bring them in to common shirq.c. Also updated the corresponding documentation for DT binding of shirq. Signed-off-by: NShiraz Hashim <shiraz.hashim@st.com> Signed-off-by: NViresh Kumar <viresh.kumar@linaro.org>

Commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code) have enabled the pendown GPIO debounce time setting by the below sequence: gpio_request_one() gpio_set_debounce() gpio_free() It also revealed a bug in the OMAP GPIO handling code which prevented the GPIO debounce clock to be disabled and CORE transition to low power states. Commit c9c55d92 (gpio/omap: fix off-mode bug: clear debounce settings on free/reset) fixes the OMAP GPIO handling code by making sure that the GPIO debounce clock gets disabled if no GPIO is requested from current bank. While fixing the OMAP GPIO handling code (in the right way), the above commit makes the gpio_request->set_debounce->free sequence invalid as after freeing the GPIO, the debounce settings are lost. Fix the debounce settings by moving the debounce initialization to the actual GPIO requesting code - the ads7846 driver.

Fix the video clock setting when custom timings are used with pclock <= 27MHz. Existing video clock selection uses PLL2 mode which results in a 54MHz clock whereas using the MXI mode results in a 27MHz clock (which is the one actually desired). This bug affects the Enhanced Definition (ED) support on DM644x. Without this patch, out-range signals errors are were observed on the TV when viewing ED. An out-of-range signal is often caused when the field rate is above the rate that the television will handle.

On OMAP4 boards using the TWL6030 PMIC, the sys_drm_msecure is connected to the MSECURE input of the TWL6030 PMIC. This signal controls the secure-mode operation of the PMIC. If its not mux'd correctly, some functionality of the PMIC will not be accessible since the PMIC will be in secure mode. For example, if the TWL RTC is in secure mode, most of its registers are read-only, meaning (re)programming the RTC (e.g. for wakeup from suspend) will fail. To fix, ensure the signal is properly mux'd as output when TWL is intialized. This fix is required when using recent versions of u-boot (>= v2012.04.01) since u-boot is no longer setting the default mux for this pin.

The U300 IRQs were bumped once to offset to 1 (in order to avoid using IRQ 0 which is now NO_IRQ). This was OK as we were still passing the number of irqs in the .nr_irqs field of the machine, with descriptors allocated at boot time. However .nr_irqs should be 0, leading the system to reserve the first 16 IRQs. Then the VIC driver will complain that IRQs 1 thru 15 are pre-allocated, so to avoid this and use free descriptors, move all IRQs up to offset 32. This will all be done away with as we migrate to device tree, so it is an interim solution. Acked-by: NOlof Johansson <olof@lixom.net> Signed-off-by: NLinus Walleij <linus.walleij@linaro.org>

Resolve this kernel boot message: omap_hwmod: mcpdm: cannot be enabled for reset (3) The McPDM on OMAP4 can only receive its functional clock from an off-chip source. This source is not guaranteed to be present on the board, and when present, it is controlled by I2C. This would introduce a board dependency to the early hwmod code which it was not designed to handle. Also, neither the driver for this off-chip clock provider nor the I2C code is available early in boot when the hwmod code is attempting to enable and reset IP blocks. This effectively makes it impossible to enable and reset this device during hwmod init. At its core, this patch is a workaround for an OMAP hardware problem. It should be possible to configure the OMAP to provide any IP block's functional clock from an on-chip source. (This is true for almost every IP block on the chip. As far as I know, McPDM is the only exception.) If the kernel cannot reset and configure IP blocks, it cannot guarantee a sane SoC state. Relying on an optional off-chip clock also creates a board dependency which is beyond the scope of the early hwmod code. This patch works around the issue by marking the McPDM hwmod record with the HWMOD_EXT_OPT_MAIN_CLK flag. This prevents the hwmod code from touching the device early during boot.

Add HWMOD_EXT_OPT_MAIN_CLK flag to indicate that this IP block is dependent on an off-chip functional clock that is not guaranteed to be present during initialization. IP blocks marked with this flag are left in the INITIALIZED state during kernel init. This is a workaround for a hardware problem. It should be possible to guarantee that at least one clock source will be present and active for any IP block's main functional clock. This ensures that the hwmod code can enable and reset the IP block. Resetting the IP block during kernel init prevents any bogus bootloader, ROM code, or previous OS configuration from affecting the kernel. Hopefully a clock multiplexer can be added on future SoCs. N.B., at some point in the future, it should be possible to query the clock framework for this type of information. Then this flag should no longer be needed.

When waking up from off-mode, some IP blocks are reset automatically by hardware. For this reason, software must wait until the reset has completed before attempting to access the IP block. This patch fixes for example the bug introduced by commit 6c31b215 ("mmc: omap_hsmmc: remove access to SYSCONFIG register"), in which the MMC IP block is reset during off-mode entry, but the code expects the module to be already available during the execution of context restore.

Since CAM domain (ISS) has no module wake-up dependency with any other clock domain of the device and the dynamic dependency from L3_main_2 is always disabled, the domain needs to be in force wakeup in order to be able to access it for configure (sysconfig) it or use it. Also since there is no clock in the domain managed automatically by the hardware, there is no use to configure automatic clock domain transition.
