| * mfd: axp20x: Add support for AXP15060 PMICShengyu Qu2023-04-262-0/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AXP15060 is a PMIC chip produced by X-Powers, and could be connected via an I2C bus. Describe the regmap and the MFD bits, along with the registers exposed via I2C. Eventually advertise the device using a new compatible string and add support for power off the system. The driver would disable PEK function if IRQ is not configured in device tree, since some boards (For example, Starfive Visionfive 2) didn't connect IRQ line of PMIC to SOC. GPIO function isn't enabled in this commit, since its configuration operation is different from any existing AXP PMICs and needs logic modification on existing driver. GPIO support might come in later patches.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RZ/G2L multi-function timer pulse unit 3 (MTU3a) is embedded in the Renesas RZ/G2L family SoCs. It consists of eight 16-bit timer channels and one 32-bit timer channel. It supports the following functions - Counter - Timer - PWM The 8/16/32 bit registers are mixed in each channel. Add MTU3a core driver for RZ/G2L SoC. The core driver shares the clk and channel register access for the other child devices like Counter, PWM and Clock event.

| * mfd: ocelot-spi: Fix unsupported bulk readColin Foster2023-04-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ocelot chips (VSC7511, VSC7512, VSC7513, VSC7514) don't support bulk read operations over SPI. Many SPI buses have hardware that can optimize consecutive reads. Essentially an address is written to the chip, and if the SPI controller continues to toggle the clock, subsequent register values are reported. This can lead to significant optimizations, because the time between "address is written to the chip" and "chip starts to report data" can often take a fixed amount of time. When support for Ocelot chips were added in commit f3e893626abe ("mfd: ocelot: Add support for the vsc7512 chip via spi") it was believed that this optimization was supported. However it is not. Most register transactions with the Ocelot chips are not done in bulk, so this bug could go unnoticed. The one scenario where bulk register operations _are_ performed is when polling port statistics counters, which was added in commit d87b1c08f38a ("net: mscc: ocelot: use bulk reads for stats"). Things get slightly more complicated here... A bug was introduced in commit d4c367650704 ("net: mscc: ocelot: keep ocelot_stat_layout by reg address, not offset") that broke the optimization of bulk reads. This means that when Ethernet support for the VSC7512 chip was added in commit 3d7316ac81ac ("net: dsa: ocelot: add external ocelot switch control") things were actually working "as expected". The bulk read opmtimization was discovered, and fixed in commit 6acc72a43eac ("net: mscc: ocelot: fix stats region batching") and the timing optimizations for SPI were noticed. A bulk read went from ~14ms to ~2ms. But this timing improvement came at the cost of every register reading zero due the fact that bulk reads don't work. The read timings increase back to 13-14ms, but that's a price worth paying in order to receive valid data. This is verified in a DSA setup (cpsw-new switch tied to port 0 on the VSC7512, after having been running overnight) Rx Octets: 16222055 # Counters from CPSW switch Tx Octets: 12034702 Net Octets: 28256757 p00_rx_octets: 12034702 # Counters from Ocelot switch p00_rx_frames_below_65_octets: 0 p00_rx_frames_65_to_127_octets: 88188 p00_rx_frames_128_to_255_octets: 13 p00_rx_frames_256_to_511_octets: 0 p00_rx_frames_512_to_1023_octets: 0 p00_rx_frames_over_1526_octets: 3306 p00_tx_octets: 16222055 Fixes: f3e893626abe ("mfd: ocelot: Add support for the vsc7512 chip via spi") Signed-off-by: Colin Foster <colin.foster@in-advantage.com> Signed-off-by: Lee Jones <lee@kernel.org> Link: https://lore.kernel.org/r/20230322141130.2531256-1-colin.foster@in-advantage.com

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The I2C_DETECT register is at IO port 0x1a7, which is outside the range passed to devm_ioport_map() for io_base, and was only working because there aren't actually any bounds checks for IO port accesses. Extending the range does not seem like a good solution here, as it would then conflict with the IO resource assigned to the I2C controller. As this is just a one-off access during probe, use a simple inb() instead. While we're at it, drop the unused define TQMX86_REG_I2C_INT_EN.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The usual behavior of mask registers is writing a '1' bit to disable (mask) an interrupt; similarly, writing a '1' bit to an unmask register enables (unmasks) an interrupt. Due to a longstanding issue in regmap-irq, mask and unmask registers were inverted when both kinds of registers were present on the same chip, ie. regmap-irq actually wrote '1's to the mask register to enable an IRQ and '1's to the unmask register to disable an IRQ. This was fixed by commit e8ffb12e7f06 ("regmap-irq: Fix inverted handling of unmask registers") but the fix is opt-in via mask_unmask_non_inverted = true because it requires manual changes for each affected driver. The new behavior will become the default once all drivers have been updated. The PM8008 appears to rely on the inverted behavior. It has separate set & clear registers for a register called INT_EN, which presumably enables interrupts by writing '1's. Opt in to the new non-inverted behavior & swap mask_base/unmask_base.
