2024-08-31memory: renesas-rpc-if: Use Hi-Z state as the default setting for IOVF pinsBiju Das1-1/+1
The RZ/{G2L,G2LC,V2L} SMARC EVK uses Micron MT25QU412A flash and RZ/G2UL SMARC EVK uses Renesas AT25QL128A flash. With current pin setting for IOVF pin, 4-bit flash write fails for AT25QL128A flash. Use Hi-Z state as the default for IOVF pin, so that spi controller driver in linux will be independent of flash type. To support this, during board production, the bit 4 of the NV config register must be cleared by the bootloader for Micron flash. Output from u-boot after clearing bit4 of NVCR register. => renesas_micron_flash_nvcr SF: Detected mt25qu512a with page size 256 Bytes, erase size 64 KiB, total 64 MiB NVCR=0xef Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com> Link: https://lore.kernel.org/r/20240830203014.199326-2-biju.das.jz@bp.renesas.com Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

2024-08-25memory: ti-aemif: Revert "memory: ti-aemif: don't needlessly iterate over ↵Bartosz Golaszewski1-3/+5
child nodes" This reverts commit 23a641d5c2bce4c723fff9118a5d865ee6b9d05a. The first-level children of the aemif node are not the device nodes (ones containing the 'compatible' property) but the chip-select nodes which instead have their own children. of_platform_populate() will skip such nodes so we must indeed iterate over the direct children of the aemif node. The problem here is that we never call of_platform_depopulate() as it takes the root device as argument. We only have an unpopulated chip-select nodes so we will leak these devices if any of the calls to of_platform_populate() fails. I don't have a batter idea right now but my patch was not correct so we need to revert it. While at it: at least use the scoped variant of the OF node iterator. Down the line, we should find a better solution to fix this potential resource leak in error path.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc Pull char/misc and other driver subsystem updates from Greg KH: "Here is the big set of char/misc and a number of other driver subsystem updates for 6.9-rc1. Included in here are: - IIO driver updates, loads of new ones and evolution of existing ones - coresight driver updates - const cleanups for many driver subsystems - speakup driver additions - platform remove callback void cleanups - mei driver updates - mhi driver updates - cdx driver updates for MSI interrupt handling - nvmem driver updates - other smaller driver updates and cleanups, full details in the shortlog All of these have been in linux-next for a long time with no reported issue, other than a build warning for the speakup driver" The build warning hits clang and is a gcc (and C23) extension, and is fixed up in the merge.

2024-02-27memory: stm32-fmc2-ebi: add MP25 RIF supportChristophe Kerello1-4/+220
The FMC2 revision 2 supports security and isolation compliant with the Resource Isolation Framework (RIF). From RIF point of view, the FMC2 is composed of several independent resources, listed below, which can be assigned to different security and compartment domains: - 0: Common FMC_CFGR register. - 1: EBI controller for Chip Select 1. - 2: EBI controller for Chip Select 2. - 3: EBI controller for Chip Select 3. - 4: EBI controller for Chip Select 4. - 5: NAND controller.

2024-02-27memory: stm32-fmc2-ebi: add MP25 supportChristophe Kerello1-12/+350
Add the support of the revision 2 of FMC2 IP. - PCSCNTR register has been removed, - CFGR register has been added, - the bit used to enable the IP has moved from BCR1 to CFGR, - the timeout for CEx deassertion has moved from PCSCNTR to BCRx, - the continuous clock enable has moved from BCR1 to CFGR, - the clk divide ratio has moved from BCR1 to CFGR. The MP1 SoCs have only one signal to manage all the controllers (NWAIT). The MP25 SOC has one RNB signal for the NAND controller and one NWAIT signal for the memory controller. Let's use a platform data structure for parameters that will differ between MP1 and MP25.

2024-02-26interconnect: constify of_phandle_args in xlateKrzysztof Kozlowski8-8/+8
The xlate callbacks are supposed to translate of_phandle_args to proper provider without modifying the of_phandle_args. Make the argument pointer to const for code safety and readability.

2024-02-22memory: tegra: Correct DLA client namesJon Hunter1-8/+8
Some of the names for the Tegra234 DLA clients are not unique and do not align with the name of the client ID definitions. Therefore, it is not possible to determine the exact DLA client from messages that print the client name. Fix this by correcting the DLA memory client names for Tegra234 to align with the name of the corresponding memory client ID. Note that although the client names are also used by the interconnect framework, interconnect support for the DLA clients has not been added and so this issue does not impact the interconnect support.
