bus: ti-sysc: Fix no_console_suspend handling

2018-08-22T15:04:49Z

If no_console_suspend is set, we should keep console enabled during suspend. Lets fix this by only producing a warning if we can't idle hardware during suspend. Fixes: ef55f8215a78 ("bus: ti-sysc: Improve suspend and resume handling") Signed-off-by: Tony Lindgren

Pull VLA removal leftovers from Kees Cook: - bus/imx-weim: Use maximum register count to avoid VLA - drm/i2c/tda9950: Use maximum CEC message size to avoid VLA * tag 'vla-leftovers-v4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: bus: imx-weim: Remove VLA usage drm/i2c: tda9950: Remove VLA usage

bus: ti-sysc: Fix module register ioremap for larger offsets

2018-08-17T14:22:56Z

We can have the interconnect target module control registers pretty much anywhere within the module range. The current code attempts an incomplete optimization of the ioremap size but does it wrong and it only works for registers at the beginning of the module. Let's just use the largest control register to calculate the ioremap size. The ioremapped range is for most part cached anyways so there is no need for size optimization. Let's also update the comments accordingly. Fixes: 0eecc636e5a2 ("bus: ti-sysc: Add minimal TI sysc interconnect target driver") Signed-off-by: Tony Lindgren

bus: imx-weim: Remove VLA usage

2018-08-13T20:40:52Z

In the quest to remove all stack VLA usage from the kernel[1], this switches to using a maximum size and adds a sanity check.

Merge tag 'sunxi-drivers-for-4.19' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux into next/drivers

2018-07-26T07:09:43Z

Allwinner drivers changes for 4.19 There's been work for this release cycles in both the SRAM controller driver in order to support more SoCs, as part of our VPU work, but also to enable the EMAC on the A64 (that needs to poke at registers within the same register space). Some work has been needed too to represent the bus to the display engine controllers that all need an SRAM to be mapped to the CPU to be able to access those controllers' registers. * tag 'sunxi-drivers-for-4.19' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux: soc: sunxi: Add the A13, A23 and H3 system control compatibles drivers: soc: sunxi: Add support for the C1 SRAM region dt-bindings: sram: sunxi: Populate valid sections compatibles dt-bindings: sram: sunxi: Add A13, A20, A23 and H3 dedicated bindings soc: sunxi: sram: Add dt match for the A10 system-control compatible dt-bindings: sram: sunxi: Introduce new A10 binding for system-control bus: add bus driver for accessing Allwinner A64 DE2 dt-bindings: add binding for the Allwinner A64 DE2 bus soc: sunxi: sram: Add updated compatible string for A64 system control dt-bindings: sram: Rename A64 SRAM controller compatible soc: sunxi: export a regmap for EMAC clock reg on A64 Signed-off-by: Olof Johansson

bus: ti-sysc: Add support for software reset

2018-07-10T05:31:38Z

Add support for the software reset of a target interconnect module using its sysconfig and sysstatus registers. Signed-off-by: Faiz Abbas [tony@atomide.com: updated to check if sysconfig exists] Signed-off-by: Tony Lindgren

bus: ti-sysc: Add support for using ti-sysc for MCAN on dra76x

2018-07-10T05:31:27Z

The dra76x MCAN generic interconnect module has a its own format for the bits in the control registers. Therefore add a new module type, new regbits and new capabilities specific to the MCAN module. Acked-by: Rob Herring CC: Tony Lindgren Signed-off-by: Faiz Abbas Signed-off-by: Tony Lindgren

bus: ti-sysc: Use 2-factor allocator arguments

2018-07-02T11:24:44Z

This adjusts the allocator calls to use 2-factor argument call style, as done treewide already for improved defense against allocation overflows. Signed-off-by: Kees Cook Signed-off-by: Tony Lindgren
