You might find this interesting. When uploading the firmware in the
hauppauge windows driver, the i2c algo udelay is set to 3us instead of
the normal 10us. Adding this quick function:
static void cx25840_set_i2c_delay(struct i2c_client *client, int delay)
{
struct i2c_algo_bit_data *algod = client->adapter->algo_data;
algod->udelay = delay;
}
and setting it to 3 during the firmware load reduces my module load time
from ~7.9s to ~5.2s. After the firmware is sent, I return the udelay to
10. Any reason we shoudn't do this like the windows driver does?
