|

Some Allwinner boards feature an on-board eMMC with fixed 3.3V voltage
|
||||
(e.g. Banana Pi M2+), and in this case both the eMMC and the SoC are
|
||||
capable of doing 3.3V DDR transmission.
|
||||
|
||||
Add capability of 3.3V DDR when DDR is available (extra clock or new
|
||||
timing).

Subject: [PATCH v3] mmc: sunxi: remove output of virtual base address
|

|
||||
|
||||
Recent Linux versions refuse to print actual virtual kernel addresses,
|
||||
to not give a hint about the location of the kernel in a randomized virtual
|
||||
address space. This affects the output of the sunxi MMC controller
|
||||
driver, which now produces the rather uninformative line:
|
||||
|
||||
[ 1.482660] sunxi-mmc 1c0f000.mmc: base:0x(____ptrval____) irq:8
|
||||
|
||||
Since the virtual base address is not really interesting in the first
|
||||
place, let's just drop this value. The same applies to Linux' notion of
|
||||
the interrupt number, which is independent from the GIC SPI number.
|
||||
We have the physical address as part of the DT node name, which is way
|
||||
more useful for debugging purposes.
|
||||
To keep a success message in the driver, we make this purpose explicit
|
||||
with the word "initialized", plus print some information that is not too
|
||||
obvious and that we learned while probing the device:
|
||||
the maximum request size and whether it uses the new timing mode.
|
||||
So the output turns into:
|
||||
[ 1.750626] sunxi-mmc 1c0f000.mmc: initialized, max. request size: 16384 KB, uses new timings mode
|
||||
[ 1.786699] sunxi-mmc 1c11000.mmc: initialized, max. request size: 2048 KB
