lib/decompressors: use real out buf size for gunzip with kernel

2015-09-29T17:26:19+00:00

commit 2d3862d26e67a59340ba1cf1748196c76c5787de upstream.

When loading x86 64bit kernel above 4GiB with patched grub2, got kernel
gunzip error.

| decompress_kernel:
|       input: [0x807f2143b4-0x807ff61aee]

the new buffer is at 0x46fe000000ULL, decompressor_gzip is using
0xffffffb901ffffff as out_len.  gunzip in lib/zlib_inflate/inflate.c cap
that len to 0x01ffffff and decompress fails later.

We could hit this problem with crashkernel booting that uses kexec loading
kernel above 4GiB.

We have decompress_* support:
    1. inbuf[]/outbuf[] for kernel preboot.
    2. inbuf[]/flush() for initramfs
    3. fill()/flush() for initrd.
This bug only affect kernel preboot path that use outbuf[].

Add __decompress and take real out_buf_len for gunzip instead of guessing
wrong buf size.

ARM: dts: rockchip: fix rk3288 watchdog irq

2015-09-21T17:05:44+00:00

commit 1a1b698b115467242303daf5fe1d3c9886c2fa17 upstream.

The watchdog irq is actually SPI 79, which translates to the original
111 in the manual where the SPI irqs start at 32.
The current dw_wdt driver does not use the irq at all, so this issue
never surfaced. Nevertheless fix this for a time we want to use the irq.

ARM: dts: fix clock-frequency of display timing0 for exynos3250-rinato

2015-09-21T17:05:43+00:00

commit 65e3293381e1cf1abcfe1aa22b914650a40e3af4 upstream.

After the commit abc0b1447d49 ("drm: Perform basic sanity checks on
probed modes"), proper clock-frequency becomes mandatory for
validating the mode of panel.  The display does not work if there is
no mode validated. Also, this clock-frequency must be set
appropriately for getting required frame rate.

ARM: dts: OMAP5: Fix broken pbias device creation

2015-09-13T16:07:43+00:00

commit 70caac3f25291cf715cf8f2d8c7db46f6cbefe7c upstream.

commit  ("ARM: dts: omap5: add minimal l4 bus
layout with control module support") moved pbias_regulator dt node
from being a child node of ocp to be the child node of
omap5_padconf_global. After this device for pbias_regulator is
not created.

Fix it by adding "simple-bus" compatible property to
omap5_padconf_global dt node.

ARM: imx6: correct i.MX6 PCIe interrupt routing

commit 1a9fa190956f45c1e58c4d8bfa5ac051691ea590 upstream.

The PCIe interrupts are also routed through the GPC. This has been
missed from the conversion to stacked IRQ domains as the PCIe
controller uses an explicit interrupt map and thus doesn't inherit
the SoC global interrupt parent.

ARM: dts: keystone: fix dt bindings to use post div register for mainpll

2015-08-17T03:52:17+00:00

commit c1bfa985ded82cacdfc6403e78f329c44e35534a upstream.

All of the keystone devices have a separate register to hold post
divider value for main pll clock. Currently the fixed-postdiv
value used for k2hk/l/e SoCs works by sheer luck as u-boot happens to
use a value of 2 for this. Now that we have fixed this in the pll
clock driver change the dt bindings for the same.
