Subject: [PATCH RESEND v4 0/9] MIPS: Loongson: Add the Loongson-1A processor support
Date: Thu, 19 May 2016 09:38:25 +0800 [thread overview]
Message-ID: <1463621912-9883-1-git-send-email-zhoubb@lemote.com> (raw)
The Loongson 1A is similar with Loongson 1B, which is a 32-bit SoC.
It implements the MIPS32 release 2 instruction set.
They share the same PRID, so we rewrite the PRID_REV_LOONGSON1B to
PRID_REV_LOONGSON1A_1B, and use their CPU macros to distinguish.
However, the pll register of Loongson-1A is write-only, so the cpu clk
should be set manually with the command line.
The format of command is cpu_clk=osc_clk,cpu_mul
the osc_clk standby cpu clock and the cpu_mul repect the clock multiplier.
For example, we use the command cpu_clk=33333333,8
Changes since v1:
- According commit c908656a7531771ae7642990a7c5f3c7307bd612
(MIPS: Loongson: Naming style cleanup and rework) to fix the naming style.
Changes since v2:
- Remove__irq_set_handler_locked()
- Rebases on top of v4.5-rc5.
Changes since v3:
- Move ls1x CPU irq setting to driver/irqchip
- Rebases on top of v4.6-rc7.
Binbin Zhou(9):
MIPS: Loongson: Add basic Loongson-1A CPU support
MIPS: Loongson: Add Loongson-1A Kconfig options
MIPS: Loongson: Add platform devices for Loongson-1A/1B
MIPS: Loongson: Add loongson-1A board support
MIPS: Loongson-1A: workaround of pll register's write-only property
MIPS: irqchip/ls1x-cpu: Move the CPU IRQ driver from arch/mips/loongson32/common/
MIPS: Loongson-1A: Enable SPARSEMEN and HIGHMEM
MIPS: Loongson-1B: Update config file
MIPS: Loongson: Add a Loongson-1A default config file
