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. Signed-off-by:

The X-Powers AXP313a is a PMIC used on some devices with the Allwinner H616 or H313 SoC. According to the datasheet, the DC/DC converter PWM frequency is fixed (to 3 MHz), so disallow the property that lets us set this frequency for the other PMICs. Signed-off-by:

Add RZ/G2L MTU3a counter driver. This IP supports the following phase counting modes on MTU1 and MTU2 channels 1) 16-bit phase counting modes on MTU1 and MTU2 channels. 2) 32-bit phase counting mode by cascading MTU1 and MTU2 channels. This patch adds 3 counter value channels. count0: 16-bit phase counter value channel on MTU1 count1: 16-bit phase counter value channel on MTU2 count2: 32-bit phase counter value channel by cascading MTU1 and MTU2 channels. The external input phase clock pin for the counter value channels are as follows: count0: "MTCLKA-MTCLKB" count1: "MTCLKA-MTCLKB" or "MTCLKC-MTCLKD" count2: "MTCLKA-MTCLKB" or "MTCLKC-MTCLKD" Use the sysfs variable "external_input_phase_clock_select" to select the external input phase clock pin and "cascade_counts_enable" to enable/ disable cascading of channels.

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.

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 f3e89362 ("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 d87b1c08 ("net: mscc: ocelot: use bulk reads for stats"). Things get slightly more complicated here... A bug was introduced in commit d4c36765 ("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 3d7316ac ("net: dsa: ocelot: add external ocelot switch control") things were actually working "as expected". The bulk read opmtimization was discovered, and fixed in commit 6acc72a4 ("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: f3e89362 ("mfd: ocelot: Add support for the vsc7512 chip via spi") Signed-off-by:

As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message.
