* AB8500 register access
* ======================
*
* read:
* # echo BANK > <debugfs>/ab8500/register-bank
* # echo ADDR > <debugfs>/ab8500/register-address
* # cat <debugfs>/ab8500/register-value
*
* write:
* # echo BANK > <debugfs>/ab8500/register-bank
* # echo ADDR > <debugfs>/ab8500/register-address
* # echo VALUE > <debugfs>/ab8500/register-value
*
* read all registers from a bank:
* # echo BANK > <debugfs>/ab8500/register-bank
* # cat <debugfs>/ab8500/all-bank-register
*
* BANK target AB8500 register bank
* ADDR target AB8500 register address
* VALUE decimal or 0x-prefixed hexadecimal
*
*
* User Space notification on AB8500 IRQ
* =====================================
*
* Allows user space entity to be notified when target AB8500 IRQ occurs.
* When subscribed, a sysfs entry is created in ab8500.i2c platform device.
* One can pool this file to get target IRQ occurence information.
*
* subscribe to an AB8500 IRQ:
* # echo IRQ > <debugfs>/ab8500/irq-subscribe
*
* unsubscribe from an AB8500 IRQ:
* # echo IRQ > <debugfs>/ab8500/irq-unsubscribe
*
*
* AB8500 register formated read/write access
* ==========================================
*
* Read: read data, data>>SHIFT, data&=MASK, output data
* [0xABCDEF98] shift=12 mask=0xFFF => 0x00000CDE
* Write: read data, data &= ~(MASK<<SHIFT), data |= (VALUE<<SHIFT), write data
* [0xABCDEF98] shift=12 mask=0xFFF value=0x123 => [0xAB123F98]
*
* Usage:
* # echo "CMD [OPTIONS] BANK ADRESS [VALUE]" > $debugfs/ab8500/hwreg
*
* CMD read read access
* write write access
*
* BANK target reg bank
* ADDRESS target reg address
* VALUE (write) value to be updated
*
* OPTIONS
* -d|-dec (read) output in decimal
* -h|-hexa (read) output in 0x-hexa (default)
* -l|-w|-b 32bit (default), 16bit or 8bit reg access
* -m|-mask MASK 0x-hexa mask (default 0xFFFFFFFF)
* -s|-shift SHIFT bit shift value (read:left, write:right)
* -o|-offset OFFSET address offset to add to ADDRESS value
*
* Warning: bit shift operation is applied to bit-mask.
* Warning: bit shift direction depends on read or right command.

treewide: devm_kzalloc() -> devm_kcalloc() The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc(). This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant.
