keyboard: Set configuration registers

I wondered if num==0 could be used instead of a new en field, but 0 is a
valid row/column number, so no. As such,
Acked-by: Stephen Warren<swarren@xxxxxxxxxx>
Can we pass in number of pin_cfg instances in pdata and simply do not
mention unneeded pins instead?
IIUC, the array is currently a fixed size (based on the set of pins
Supported by the KBC), hence that won't work; there's an entry for each
pin saying which row/column it is.
However, I suppose if we were to change the structure of the pdata to be:
struct tegra_kbc_pin_cfg {
bool is_row;
u8 row_col_id;
u8 pin_id;
};
Then struct tegra_kbc_platform_data could indeed have a pointer to a
variable-sized array of these, which would avoid the "en" member.
How about we change bool to enum instead, like in the patch below?
*ping*
That's conceptually fine by me. I was assuming you were asking Rakesh...
Everyone... Anyone ;)
I'd rather PIN_CFG_IGNORE was the first enum, so it gets value 0, or this
probably won't solve the original issue?
The benefit of current definition is that it is compatible with old
ones using bool...
Thanks.
Sorry for delay in response.
I am OK with new definition. Agree, makes compatible with old definitions.
Thanks!
