Add GPIO driver support to Freescale VF610
Signed-off-by: Bhuvanchandra DV
-
Like SPI and I2C few GPIO controllers also have
multiple chip instances. This patch adds the
flag 'DM_UC_FLAG_SEQ_ALIAS' in gpio_uclass driver
to control device sequence numbering. By defalut
the dev->r_seq for gpio_uclass will alwalys
returns -1, which leads the gpio driver probe
failure when using the driver with device trees.Signed-off-by: Bhuvanchandra DV

The CPU temperature grade from OTP is now used to define the critical
threshold at which point we busyloop until we are below, however this
threshold is still too low.Instead of 20C below the max CPU temperature, change it to 5C defined now
by TEMPERATURE_HOT_DETLA for clarity. Rename 'passive' to 'critical'
as that better defines our use case here. Additionally change the output
of the busyloop message to show the max CPU temperature as well as current.Before:
CPU Temperature is 101 C, too hot to boot, waiting...

This changes enable ONFI detection. The Read ID command now allows
one address byte which is needed for ONFI detection. To read the
ONFI parameter page, the NAND_CMD_PARAM need to be supported. The
CMD code enables one command and one address byte along with reading
data from flash using R/B#, as specified by ONFI.Signed-off-by: Stefan Agner

Add option to choose between current 24-error correction and 32-error

Use in-band bad block table (NAND_BBT_NO_OOB) which allows to
use the full OOB for hardare ECC purposes. Since there is no
ECC correction on the OOB it is also safer to use in-band area
to store the bad block table marker.Signed-off-by: Stefan Agner
-
Implement read of OOB area only. When using column and sector size
properties, only parts of the page can be read. However, this works
only when hardware ECC is disabled, otherwise the ECC engine would
ruin the data in the buffer. To allow OOB only reads, three points
had to be addressed:
- Set ECC mode per command.
- Handle NAND_CMD_READOOB seperate. Make sure column and sector
size is correctly set up, while disabling ECC.
- Now, the OOB data end up at the beginning of the buffer. Remove
the special handling of OOB (spareonly).Especially bad block scans benefit from this change. On a 512MiB
SLC NAND device, the bad block scan took 1.5s less than before.Signed-off-by: Stefan Agner

Allow bit flips in a empty page up to half of the recoverable
bits (strength / 2).Signed-off-by: Stefan Agner
-
Since we do not support sub-page writes anyway, reading the page
back to the controller on SEQIN command is not required. Remove
the page read on SEQIN.However, the column/page values relevant to the SEQIN command, hence
set the column/row address on SEQIN command.Signed-off-by: Stefan Agner
-
To improve performance we remember the current page in the buffer
and avoid reading it twice. This implicit page cache increases
complexity while does not increase performance in real world cases.
This patch removes that feature.Acked-by: Bill Pringlemeir

On systems with caches enabled, NAND I/O may need to flush/invalidate
the cache during read/write operations. For this to work correctly, all
buffers must be cache-aligned. Fix nand_verify*() to allocate aligned
buffers.This prevents cache alignment warnings from being spewed when using
U-Boot to write an updated version of itself to flash on NVIDIA Tegra
Seaboard (after perturbation of stack/data layout in current
u-boot-dm/next branch).I have validatd (executed) nand_verify(), but I don't think I've executed
nand_verify_page_oob(); testing of that would be useful.Cc: Peter Tyser

This commit adds emulation of sandbox PMIC device, which includes:
- PMIC I2C emulation driver
- PMIC I/O driver (UCLASS_PMIC)
- PMIC regulator driver (UCLASS_REGULATOR)The sandbox PMIC has 12 significant registers and 4 as padding to 16 bytes,
which allows using 'i2c md' command with the default count (16).The sandbox PMIC provides regulators:
- 2x BUCK
- 2x LDOEach, with adjustable output:
- Enable state
- Voltage
- Current limit (LDO1/BUCK1 only)
- Operation mode (different for BUCK and LDO)Each attribute has it's own register, beside the enable state, which depends
on operation mode.The header file: sandbox_pmic.h includes PMIC's default register values,
which are set on i2c pmic emul driver's probe() method.Signed-off-by: Przemyslaw Marczak

The function get_emul() in sandbox i2c bus driver, always returns
first child as i2c emul device. This may only work for i2c devices
with a single child, which is an only i2c emul device.In case when i2c device has more than one child (e.g. PMIC), and
one is i2c emul, then the function should search it by check uclass
id for each child. This patch add this change to the get_emul().Signed-off-by: Przemyslaw Marczak

This driver implements regulator operations for fixed Voltage/Current
value regulators. beside the standard regulator constraints, which are
put into the uclass platform data, a typical fixed regulator node provides
few additional properties like:
- gpio
- gpio-open-drain
- enable-active-high
- startup-delay-us
The only 'gpio' is used by this driver and is kept in structure of type
'fixed_regulator_platdata', as a device platform data (dev->platdata).The driver implements:
- get_value
- get_current
- get_enable
- set_enableThe regulator calls and commands can be used for fixed-regulator devices,
and the proper error will be returned for prohibited.Signed-off-by: Przemyslaw Marczak

This is the implementation of driver model PMIC driver.
The max77686 PMIC driver implements read/write operations and driver
bind method - to bind its childs.This driver will try to bind the regulator devices by using it's child
info array with regulator prefixes and driver names. This should succeed
when compatible regulator driver is compiled. If no regulator driver found,
then the pmic can still provide read/write operations, and can be used with
PMIC function calls.Signed-off-by: Przemyslaw Marczak
