The y2038 issue for ppdev is changes of timeval in the ioctl
(PPSETTIME and PPGETTIME). The size of struct timeval changes from
8bytes to 16bytes due to the changes of time_t. It lead to the
changes of the command of ioctl, e.g. for PPGETTIME, We have:
on 32-bit (old): 0x80087095
on 32-bit (new):
The arg of ioctl in ppdev is the pointer of integer except the
timeval in PPSETTIME, PPGETTIME. Different size of timeval
is already supported by the previous patches. So, it is safe
to add compat support.

This patch adds the bus device-tree node of INT (internal) block
to enable the bus frequency. The following sub-blocks share
the VDD_INT power source:
- LEFTBUS (parent device)
- RIGHTBUS
- PERIL
- LCD0
- FSYS
- MCUISP / ISP
- MFC
The LEFTBUS is parent device with devfreq ondemand governor

This patch adds the support of bus frequency feature for sub-blocks which share
the one power line. If each bus depends on the power line, each bus is not able
to change the voltage by oneself. To optimize the power-consumption on runtime,
some buses using the same power line should change the sour
Hi, Don,
I am interested in the perf c2c tool, which is introduced in:

However, I found that this tool has not been applied to the mainline tree of
perf, Why? It was first
introduced in Feb. 2014. What's its current status now? Does it have a new

which includes the devfreq-events and regulator properties. The bus

This patch modifies the following sysfs entry of DEVFREQ framework
because the devfreq device using passive governor don't need the same

This patch adds the bus nodes for Exynos4210 SoC. Exynos4210 SoC has
one power line for all buses to translate data between DRAM and sub-blocks.
Following list specifies the detailed relation between DRAM and sub-blocks:
- DMC/ACP clock for DMC (Dynamic Memory Controller)
- ACLK200 clock for LCD0
This patch adds the bus noes using VDD_INT for Exynos4x12 SoC.
Exynos4x12 has the following AXI buses to translate data between
DRAM and sub-blocks.
Following list specifies the detailed relation between DRAM and sub-blocks:
- ACLK100 clock for PERIL/PERIR/MFC(PCLK)
- ACLK160 clock for CAM/TV/LCD
This patch updates the documentation for passive bus devices and adds the
detailed example of Exynos3250.
