[PATCH 2/2] riscv: Enable generic clockevent broadcast

From: Guo Ren When percpu-timers are stopped by deep power saving mode, we need system timer help to broadcast IPI_TIMER. This is first introduced by broken x86 hardware, where the local apic timer stops in C3 state. But many other architectures(powerpc, mips, arm, hexagon, openrisc, sh) have su

[PATCH v2] Expose the bus kernel docs to the build docs.

Before, the bus type related APIs that were defined in the include/linux/device/bus.h were not referenced anywhere in the docs, so I linked it to the bus types api documentation. Signed-off-by: Wren Turkal --- Documentation/driver-api/driver-model/bus.rst | 8 Documentation/driver-api/i

[PATCH 0/2] sun8i: r40: second ethernet support

This patch series adds support for two Ethernet ports on Allwinner R40. R40 (aka V40,A40i,T3) has two different Ethernet IPs called EMAC and GMAC. EMAC only support 10/100 Mbit in MII mode, while GMAC support both 10/100 (MII) and 10/100/1000 (RGMII). In contrast to A10/A20 where GMAC and EMAC

Upstream a long-standing OpenWrt patch [0] that fixes MT7620 PCIe PLL lock check. The existing code checks the wrong register bit: PPLL_SW_SET is not defined in PPLL_CFG1 and bit 31 of PPLL_CFG1 is marked as reserved in the MT7620 Programming Guide. The correct bit to check for PLL lock is PPLL_LD

[PATCH] MIPS: ralink: make RALINK_ILL_ACC symbol visible

The illegal access driver is optional - it is informational and does not provide critical functionality. Furthermore, it is currently not functional on RT5350 SoCs, so a user may choose to omit non-functional code on that platform. The default is kept at 'y' for backwards compatibility. This change

LLD defines .TOC. as the .got input section plus 0x8000. When CONFIG_PPC_
