Replaces all occurrences of em28xx_write_regs_req() and em28xx_write_reg()
used to setup register names by em28xx_write_reg().
Also, documents the register names that are known.
This patch were generated by this small perl script:
my %reg_map = (
# Register table - the same as defined on parse_em28xx.pl script
);
while (<>) {
if (m/(.*)em28xx_write_regs_req\(dev\,\s*0x00\,\s*(.*)\,\s*\"\\x(..)\",\s*1\)\;(.*)/) {
my $reg = $2;
my $val = $3;
$val =~ tr/A-f/a-f/;
$reg = $reg_map{$reg} if defined($reg_map{$reg});
printf "$1em28xx_write_reg(dev, %s, 0x%s);$4\n", $reg, $val;
} elsif (m/(.*)em28xx_write_regs\(dev\,\s*(.*)\,\s*\"\\x(..)\",\s*1\)\;(.*)/) {
my $reg = $2;
my $val = $3;
$val =~ tr/A-f/a-f/;
$reg = $reg_map{$reg} if defined($reg_map{$reg});
printf "$1em28xx_write_reg(dev, %s, 0x%s);$4\n", $reg, $val;
} else {
print $_;
}
