2020-05-18gpio: mb86s7x: Use devm_clk_get_optional() to get the input clockAndy Shevchenko1-9/+7
Simplify the code which fetches the input clock by using devm_clk_get_optional(). If no input clock is present devm_clk_get_optional() will return NULL instead of an error which matches the behavior of the old code.

2020-05-16gpiolib: Document that GPIO line names are not globally uniqueGeert Uytterhoeven1-3/+8
gpiochip_set_desc_names() no longer rejects GPIO line name collisions. Hence GPIO line names are not guaranteed to be globally unique. In case of multiple GPIO lines with the same name, gpio_name_to_desc() will return the first match found. Update the comments for gpio_name_to_desc() and gpiochip_set_desc_names() to match reality.

2020-04-29gpio: pca953x: fix handling of automatic address incrementingUwe Kleine-König1-16/+28
Some of the chips supported by the pca953x driver need the most significant bit in the address word set to automatically increment the address pointer on subsequent reads and writes (example: PCA9505). With this bit unset the same register is read multiple times on a multi-byte read sequence. Other chips must not have this bit set and autoincrement always (example: PCA9555). Up to now this AI bit was interpreted to be part of the address, which resulted in inconsistent regmap caching when a register was written with AI set and then read without it. This happened for the PCA9505 in pca953x_gpio_set_multiple() where pca953x_read_regs() bulk read from the cache for registers 0x8-0xc and then wrote to registers 0x88-0x8c. (Side note: reading 5 values from offset 0x8 yiels OP0 5 times because AI must be set to get OP0-OP4, which is another bug that is resolved here as a by-product.) The same problem happens when calls to gpio_set_value() and gpio_set_array_value() were mixed. With this patch the AI bit is always set for chips that support it. This works as there are no code locations that make use of the behaviour with AI unset (for the chips that support it). Note that the call to pca953x_setup_gpio() had to be done a bit earlier to make the NBANK macro work. The history of this bug is a bit complicated. Commit b32cecb46bdc ("gpio: pca953x: Extract the register address mangling to single function") changed which chips and functions are affected. Commit 3b00691cc46a ("gpio: pca953x: hack to fix 24 bit gpio expanders") used some duct tape to make the driver at least appear to work. Commit 49427232764d ("gpio: pca953x: Perform basic regmap conversion") introduced the caching. Commit b4818afeacbd ("gpio: pca953x: Add set_multiple to allow multiple bits to be set in one write.") introduced the .set_multiple() callback which didn't work for chips that need the AI bit which was fixed later for some chips in 8958262af3fb ("gpio: pca953x: Repair multi-byte IO address increment on PCA9575"). So I'm sorry, I don't know which commit I should pick for a Fixes: line.

The commit 96d7c7b3e654 ("gpio: gpio-pca953x, Add get_multiple function") basically did everything wrong from style and code reuse perspective, i.e. - it didn't utilize existing PCA953x internal helpers - it didn't utilize bitmap API - it misses the point that ilog2(), besides that BANK_SFT is useless, can be used in macros - it has indentation issues.

2020-04-17dt-bindings: gpio: Convert snps,dw-apb-gpio to DT schemaSerge Semin2-65/+129
Modern device tree bindings are supposed to be created as YAML-files in accordance with DT schema. This commit replaces Synopsys DW GPIO legacy bare text binding with YAML file. As before the binding file states that the corresponding dts node is supposed to be compatible with generic DW I2C controller indicated by the "snps,dw-apb-gpio" compatible string and to provide a mandatory registers memory range. It may also have an optional clock and reset phandle references. There must be specified at least one subnode with "snps,dw-apb-gpio-port" compatible string indicating the GPIO port, which would actually export the GPIO controller functionality. Such nodes should have traditional GPIO controller properties together with optional interrupt-controller attributes if the corresponding controller was synthesized to detect and report the input values change to the parental IRQ controller.

2020-04-16gpio: gpio-pca953x, Add get_multiple functionPaul Thomas1-0/+37
Implement a get_multiple function for gpio-pca953x. If a driver leaves get_multiple unimplemented then gpio_chip_get_multiple() in gpiolib.c takes care of it by calling chip->get() as needed. For i2c chips this is very inefficient. For example if you do an 8-bit read then instead of a single i2c transaction there are 8 transactions reading the same byte!

2020-04-15gpiolib: of: improve gpiolib-of support of pull up/down on expandersAdam Ford1-0/+10
When using GPIO expanders attached to I2C ports, their set_config function needs to be passed a config setting which contains options to enable pull up or pull down bias feature. In order to set this config properly, the gpio parser needs to handle GPIO_PULL_UP and GPIO_PULL_DOWN. This patch enables the flags corresponding to GPIO_PULL_UP and GPIO_PULL_DOWN.

2020-04-14gpio: xgene-sb: set valid IRQ type in to_irq()Brian Masney1-1/+1
xgene-sb is setup to be a hierarchical IRQ chip with the GIC as the parent chip. xgene_gpio_sb_to_irq() currently sets the default IRQ type to IRQ_TYPE_NONE, which the GIC loudly complains about with a WARN_ON(). Let's set the initial default to a sane value (IRQ_TYPE_EDGE_RISING) that was determined by decoding the ACPI tables on affected hardware: Device (_SB.GPSB) { Name (_HID, "APMC0D15") // _HID: Hardware ID Name (_CID, "APMC0D15") // _CID: Compatible ID Name (_UID, "GPIOSB") // _UID: Unique ID ... Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings { ... Interrupt (ResourceConsumer, Edge, ActiveHigh, Exclusive, ,, ) { 0x00000048, } ... } } This can be overridden later as needed with irq_set_irq_type().
