Add SoC macro ARCH_KUNPENG50X, and the Kunpeng L3 cache controller only enabled on that platform. 2. Require the compatible string of the Kunpeng L3 cache controller must have a relevant name on a specific SoC. For example: compatible = "hisilicon,kunpeng509-l3cache", "hisilicon,kunpeng-l3cache"; v3 --> v4: Rename the compatible string from "hisilicon,l3cache" to "hisilicon,kunpeng-l3cache". Then adjust the file name, configuration option name, and description accordingly. v2 --> v3: Add Hisilicon L3 cache controller driver and its document. That's: patch 2-3. v1 --> v2: Discard the middle-tier functions and do silent narrowing cast in the outcache hook functions. For example: -static void l2c220_inv_range(unsigned long start, unsigned long end) +static void l2c220_inv_range(phys_addr_t pa_start, phys_addr_t pa_end) { + unsigned long start = pa_start; + unsigned long end = pa_end; v1: Do cast phys_addr_t to unsigned long by adding a middle-tier function. For example: -static void l2c220_inv_range(unsigned long start, unsigned long end) +static void __l2c220_inv_range(unsigned long start, unsigned long end) { ... } +static void l2c220_inv_range(phys_addr_t start, phys_addr_t end) +{ + __l2c220_inv_range(start, end); +} Zhen Lei (4): ARM: LPAE: Use phys_addr_t instead of unsigned long in outercache hooks ARM: hisi: add support for Kunpeng50x SoC dt-bindings: arm: hisilicon: Add binding for Kunpeng L3 cache controller ARM: Add support for Hisilicon Kunpeng L3 cache controller .../arm/hisilicon/kunpeng-l3cache.yaml | 40 +++++ arch/arm/include/asm/outercache.h | 6 +- arch/arm/mach-hisi/Kconfig | 8 + arch/arm/mm/Kconfig | 10 ++ arch/arm/mm/Makefile | 1 + arch/arm/mm/cache-feroceon-l2.c | 15 +- arch/arm/mm/cache-kunpeng-l3.c | 153 ++++++++++++++++++ arch/arm/mm/cache-kunpeng-l3.h | 30 ++++ arch/arm/mm/cache-l2x0.c | 50 ++++-- arch/arm/mm/cache-tauros2.c | 15 +- arch/arm/mm/cache-uniphier.c | 6 +- arch/arm/mm/cache-xsc3l2.c | 12 +- 12 files changed, 317 insertions(+), 29 deletions(-) create mode 100644 Documentation/devicetree/bindings/arm/hisilicon/kunpeng-l3cache.yaml create mode 100644 arch/arm/mm/cache-kunpeng-l3.c create mode 100644 arch/arm/mm/cache-kunpeng-l3.h
