| | | | | | | | | | | | | | | | | | | | | | | | 'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.

Add handling of external wakeup interrupts mask inside the pin controller driver. Existing solution is spread between the driver and machine code. The machine code writes the mask but its value is taken from pin controller driver. This moves everything into pin controller driver allowing later to remove the cross-subsystem interaction. Also this is a necessary step for implementing later Suspend to RAM on ARMv8 Exynos5433. 2. Bring necessary suspend/resume callbacks for Exynos542x and Exynos5260. 3. Document hidden requirement about one external wakeup interrupts device node. 4. Minor documentation cleanups.

On S5Pv210 these are gph0-gph3. On all ARMv7 Exynos designs these are gpx0-gpx3. There is only one 32-bit register for controlling the external wakeup interrupt mask (masking and unmasking waking capability of these interrupts). This lead to implementation in pinctrl driver and machine code which was using static memory for storing the mask value and not caring about multiple devices of pin controller... because only one pin controller device will be handling this. Since each pin controller node in Device Tree maps onto one device, this corresponds to hidden assumption in parsing the Device Tree: external wakeup interrupts can be defined only once. Make this assumption an explicit requirement. ARMv8 Exynos5433 and Exynos7 bring additional 32 external wakeup interrupts (up to 64 total, banks gpa0-gpa3 and gpf1-gpf5) and another 32-bit wide register for controlling them. Existing code does not support it but anyway these additional interrupts will be belonging to the same pin controller device/node.

Usually, this value is expressed in mA. Since the numeric value depends on VDDIOP voltage, a value we can't retrieve at runtime, the controller uses low, medium and high to define the drive strength. The PIO controller accepts two values for the low drive configuration: 0 and 1. Most of the time, we don't care about the drive strength. So we keep the default value which is 0. The drive strength is advertised through the sysfs only when it has been explicitly set in the device tree i.e. if its value is different from 0.

Due to interactions within gpiolib code, this causes the pinctrl-msm driver to bail out (-517) during boot when a gpio-hog is declared. This can be fatal and cause the system to not boot or reset (for a detailed explanation and call-trace, refer to patch: "pinctrl: msm: fix gpio-hog related boot issues" in this series). gpio-reserved-ranges: The binding has been added as a precaution since the TrustZone firmware (aka QSEE), which is running as the hypervisor, might have reserved certain, but undisclosed pins. Hence reading or writing to the registers for those pins will cause an XPU violation and this subsequently crashes the kernel.

Some prior mostly-related discussions: http://lists.infradead.org/pipermail/linux-mtd/2013-March/046343.html [PATCH 1/3] mtd: m25p80: utilize dedicated 4-byte addressing commands http://lists.infradead.org/pipermail/barebox/2014-September/020682.html [RFC] MTD m25p80 3-byte addressing and boot problem http://lists.infradead.org/pipermail/linux-mtd/2015-February/057683.html [PATCH 2/2] m25p80: if supported put chip to deep power down if not used Previously, attempts to add reboot-time software reset handling were rejected, but the latest attempt was not. Quick summary of the problem: Some systems (e.g., boot ROM or bootloader) assume that they can read initial boot code from their SPI flash using 3-byte addressing. If the flash is left in 4-byte mode after reset, these systems won't boot. The above patch provided a shutdown/remove hook to attempt to reset the addressing mode before we reboot. Notably, this patch misses out on huge classes of unexpected reboots (e.g., crashes, watchdog resets). Unfortunately, it is essentially impossible to solve this problem 100%: if your system doesn't know how to reset the SPI flash to power-on defaults at initialization time, no amount of software can really rescue you -- there will always be a chance of some unexpected reset that leaves your flash in an addressing mode that your boot sequence didn't expect. While it is not directly harmful to perform hacks like the aforementioned commit on all 4-byte addressing flash, a properly-designed system should not need the hack -- and in fact, providing this hack may mask the fact that a given system is indeed broken. So this patch attempts to apply this unsound hack more narrowly, providing a strong suggestion to developers and system designers that this is truly a hack. With luck, system designers can catch their errors early on in their development cycle, rather than applying this hack long term. But apparently enough systems are out in the wild that we still have to provide this hack. Document a new device tree property to denote systems that do not have a proper hardware (or software) reset mechanism, and apply the hack (with a loud warning) only in this case.

In addition to the existing clock, this commit adds more clocks based on the IP specification. According to the Denali User's Guide, this IP needs three clocks: - clk: controller core clock - clk_x: bus interface clock - ecc_clk: clock at which ECC circuitry is run The driver should accept the current single clock for the backward compatibility, but the DT binding should represent the real hardware, and future platforms must follow this.
