This patch fixes Smatch static checker warning. CDNS_XSPI_CMD_REG_5 is used in ACMD mode and currently only STIG mode is enabled which doesn't use CDNS_XSPI_CMD_REG_5 and hence everything was working in STIG mode. Since plan is to use same function cdns_xspi_trigger_command() in ACMD mode, increasing size of the array passed to it.

In commit 7e71b854 ("arm64: dts: ls1028a: fix node name for the sysclk") the sysclk node name was renamed and broke the erratum workaround because it tries to fetch a device tree node by its name, which is very fragile in general. We don't even need the sysclk node because the only possible sysclk frequency input is 100MHz. In fact, the erratum says it applies if SYS_PLL_RAT is 3, not that the platform clock is 300 MHz. Make the workaround more reliable and just drop the unneeded sysclk lookup. For reference, the error during the bootup is the following: [ 4.898400] nxp-fspi 20c0000.spi: Errata cannot be executed.

Add support to read the data from the flash using external DMA. Cadence Octal SPI Flash Controller has optional DMA peripheral interface to communicate indirect mode of operations with external DMA. Xilinx Versal OSPI has external DMA enabled, this will automatically request the external DMA to fetch the data from SRAM. It supports only reading the data from SRAM (DMA read) and doesn't support writing the data to SRAM (DMA write). Xilinx Versal OSPI read the data from the flash device using external DMA and write the data to the flash device using software triggered indirect mode.

Add OSPI support for Xilinx Versal SoCs. Disable the Direct Access Controller for Xilinx Versal OSPI. On Xilinx Versal platform, AXI interface need to be selected as Linear mode (driven from interconnect rather than external DMA) to use Software triggered 'indirect' mode of operation. This will be achieved by calling Xilinx firmware API.

Merge series "add support for Cadence's XSPI controller" from Parshuram Thombare <pthombar@cadence.com>: This patch series adds support for Cadence's XSPI controller. It supports 3 work modes. 1. ACMD (auto command) work mode ACMD name is because it uses auto command engine in the controller. It further has 2 modes PIO and CDMA (command DMA). The CDMA work mode is dedicated for high-performance application where very low software overhead is required. In this mode the Command Engine is programmed by the series of linked descriptors stored in system memory. These descriptors provide commands to execute and store status information for finished commands. The PIO mode work mode is dedicated for single operation where constructing a linked list of descriptors would require too much effort. 2. STIG (Software Triggered Instruction Generator) work mode In STIG mode, controller sends low-level instructions to memory. Each instruction is 128-bit width. There is special instruction DataSequence which carries information about data phase. Driver uses Slave DMA interface to transfer data as only this interface can be used in STIG work mode. 3. Direct work mode This work mode allows sending data without invoking any command through the slave interface. Currently only STIG work mode is enabled, remaining work modes will be added later. Changes since v5: 1. Added adjust_op_size to adjust op size according to sdma size. Changes since v4: 1. Changed reg region names and lengths as suggested by Rob. Changes since v3: 1. Removed ACMD PIO mode. 2. Return IRQ_HANDLED only for handled interrupts. 3. DT binding changes. Changes since v2: 1. Removed extra lock around exec_op. 2. Removed PHY parameters setting from the driver, those will be handled by bootstrap pins available in the controller. Changes since v1: 1. Use ACMD PIO work mode for NOR read, program and erase operations, for everything else use STIG(Software Triggered Instruction Generator) work mode. 2. Changes suggested by Lukas.

Pull staging driver fixes from Greg KH: "Here are two small staging driver fixes for 5.15-rc3: - greybus tty use-after-free bugfix - r8188eu ioctl overlap build warning fix Note, the r8188eu ioctl has been entirely removed for 5.16-rc1, but it's good to get this fixed now for people using this in 5.15. Both of these have been in linux-next for a while with no reported issues" * tag 'staging-5.15-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: staging: r8188eu: fix -Wrestrict warnings staging: greybus: uart: fix tty use after free

We get an unexpected value of /proc/sys/vm/overcommit_memory after running the following program: int main() { int fd = open("/proc/sys/vm/overcommit_memory", O_RDWR); write(fd, "1", 1); write(fd, "2", 1); close(fd); } write(fd, "2", 1) will pass *ppos = 1 to proc_dointvec_minmax. proc_dointvec_minmax will return 0 without setting new_policy. t.data = &new_policy; ret = proc_dointvec_minmax(&t, write, buffer, lenp, ppos) -->do_proc_dointvec -->__do_proc_dointvec if (write) { if (proc_first_pos_non_zero_ignore(ppos, table)) goto out; sysctl_overcommit_memory = new_policy; so sysctl_overcommit_memory will be set to an uninitialized value. Check whether new_policy has been changed by proc_dointvec_minmax.
