2019-09-22Merge tag 'mips_5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linuxLinus Torvalds3-544/+0
Pull MIPS updates from Paul Burton: "Main MIPS changes: - boot_mem_map is removed, providing a nice cleanup made possible by the recent removal of bootmem. - Some fixes to atomics, in general providing compiler barriers for smp_mb__{before,after}_atomic plus fixes specific to Loongson CPUs or MIPS32 systems using cmpxchg64(). - Conversion to the new generic VDSO infrastructure courtesy of Vincenzo Frascino. - Removal of undefined behavior in set_io_port_base(), fixing the behavior of some MIPS kernel configurations when built with recent clang versions. - Initial MIPS32 huge page support, functional on at least Ingenic SoCs. - pte_special() is now supported for some configurations, allowing among other things generic fast GUP to be used. - Miscellaneous fixes & cleanups. And platform specific changes: - Major improvements to Ingenic SoC support from Paul Cercueil, mostly enabled by the inclusion of the new TCU (timer-counter unit) drivers he's spent a very patient year or so working on. Plus some fixes for X1000 SoCs from Zhou Yanjie. - Netgear R6200 v1 systems are now supported by the bcm47xx platform. - DT updates for BMIPS, Lantiq & Microsemi Ocelot systems" * tag 'mips_5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: (89 commits) MIPS: Detect bad _PFN_SHIFT values MIPS: Disable pte_special() for MIPS32 with RiXi MIPS: ralink: deactivate PCI support for SOC_MT7621 mips: compat: vdso: Use legacy syscalls as fallback MIPS: Drop Loongson _CACHE_* definitions MIPS: tlbex: Remove cpu_has_local_ebase MIPS: tlbex: Simplify r3k check MIPS: Select R3k-style TLB in Kconfig MIPS: PCI: refactor ioc3 special handling mips: remove ioremap_cachable mips/atomic: Fix smp_mb__{before,after}_atomic() mips/atomic: Fix loongson_llsc_mb() wreckage mips/atomic: Fix cmpxchg64 barriers MIPS: Octeon: remove duplicated include from dma-octeon.c firmware: bcm47xx_nvram: Allow COMPILE_TEST firmware: bcm47xx_nvram: Correct size_t printf format MIPS: Treat Loongson Extensions as ASEs MIPS: Remove dev_err() usage after platform_get_irq() MIPS: dts: mscc: describe the PTP ready interrupt MIPS: dts: mscc: describe the PTP register range ...

2019-07-25mtd: rawnand: ingenic: Add of_node_put() before returnNishka Dasgupta1-0/+1
Each iteration of for_each_child_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the return. Issue found with Coccinelle. Signed-off-by: Nishka Dasgupta <nishkadg.linux@gmail.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>

If MTD_NAND_JZ4780 is y and MTD_NAND_JZ4780_BCH is m, which select CONFIG_MTD_NAND_INGENIC_ECC to m, building fails: drivers/mtd/nand/raw/ingenic/ingenic_nand.o: In function `ingenic_nand_remove': ingenic_nand.c:(.text+0x177): undefined reference to `ingenic_ecc_release' drivers/mtd/nand/raw/ingenic/ingenic_nand.o: In function `ingenic_nand_ecc_correct': ingenic_nand.c:(.text+0x2ee): undefined reference to `ingenic_ecc_correct' To fix that, the ingenic_nand and ingenic_ecc modules have been fused into one single module. - The ingenic_ecc.c code is now compiled in only if $(CONFIG_MTD_NAND_INGENIC_ECC) is set. This is now a boolean instead of tristate. - To avoid changing the module name, the ingenic_nand.c file is moved to ingenic_nand_drv.c. Then the module name is still ingenic_nand. - Since ingenic_ecc.c is no more a module, the module-specific macros have been dropped, and the functions are no more exported for use by the ingenic_nand driver.

2019-04-18mtd: rawnand: Change Kconfig titles and re-order a bit the listMiquel Raynal1-2/+2
This list is a mess, while some items should probably not be in the raw/ sub-directory, others are definitely at the right place but not with the right description. Write uniform titles and group IPs by vendor. NAND controllers will appear under the list named "Raw/parallel NAND flash controllers" while the other drivers will appear under "Misc". Software ECC engines will later be moved out of the raw/ directory. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>

2019-04-08mtd: rawnand: ingenic: Separate top-level and SoC specific codePaul Cercueil7-203/+310
The ingenic-nand driver uses an API provided by the jz4780-bch driver. This makes it difficult to support other SoCs in the jz4780-bch driver. To work around this, we separate the API functions from the SoC-specific code, so that these API functions are SoC-agnostic.
